Manatis Karibik-Manati: Sanfte und verschmuste Riesen
Die Rundschwanzseekühe, abgeleitet von der karibisch-spanischen Bezeichnung Manatí auch Manatis genannt, sind eine Familie aquatisch lebender Säugetiere. Zusammen mit den Gabelschwanzseekühen oder Dugongs bilden sie die Ordnung der Seekühe. Die Rundschwanzseekühe (Trichechidae), abgeleitet von der karibisch-spanischen Bezeichnung Manatí auch Manatis genannt, sind eine Familie aquatisch. Der Karibik- oder Nagel-Manati (Trichechus manatus) ist eine Seekuhart aus der Familie der Rundschwanzseekühe (Trichechidae). Seekühe wie der Amazonas Manati gehen es gern gemütlich an – sind Bootsunfälle sind für viele Todesfälle von Manatis verantwortlich. Deshalb müssen Manatis jeden Tag bis zu 15% ihres Körpergewichtes an Pflanzen aufnehmen. Sanfte Riesen in Gefahr. Die geselligen Manatis leben in.

The lips use seven muscles to manipulate and tear at plants. Manatees use their lips and front flippers to move the plants into the mouth. The manatee does not have front teeth, however, behind the lips, on the roof of the mouth, there are dense, ridged pads.
These horny ridges, and the manatee's lower jaw, tear through ingested plant material. Manatees have four rows of teeth. There are 6 to 8 high-crowned, open-rooted molars located along each side of the upper and lower jaw giving a total of 24 to 32 flat, rough-textured teeth.
Eating gritty vegetation abrades the teeth, particularly the enamel crown; however, research indicates that the enamel structure in manatee molars is weak.
To compensate for this, manatee teeth are continually replaced. When anterior molars wear down, they are shed. Posterior molars erupt at the back of the row and slowly move forward to replace these like enamel crowns on a conveyor belt, similarly to elephants.
This process continues throughout the manatee's lifetime. The rate at which the teeth migrate forward depends on how quickly the anterior teeth abrade.
Manatees inhabit the shallow, marshy coastal areas and rivers of the Caribbean Sea and the Gulf of Mexico T. West Indian manatees prefer warmer temperatures and are known to congregate in shallow waters.
They frequently migrate through brackish water estuaries to freshwater springs. Their natural source for warmth during winter is warm, spring-fed rivers.
The coast of the state of Georgia is usually the northernmost range of the West Indian manatees because their low metabolic rate does not protect them in cold water.
A manatee was spotted in the Wolf River harbor near the Mississippi River in downtown Memphis in , and was later found dead 10 miles downriver in McKellar Lake.
In winter, manatees often gather near the warm-water outflows of power plants along the Florida coast, instead of migrating south as they once did.
Some conservationists are concerned that these manatees have become too reliant on these artificially warmed areas. Fish and Wildlife Service is trying to find a new way to heat the water for manatees that depended on plants that have closed.
Studies suggest that Florida manatees need access to fresh water for proper regulation of water and salts in their bodies. Accurate population estimates of the Florida manatee T.
They have been called scientifically weak [32] because they vary widely from year to year, some areas showing increases, others decreases, and little strong evidence of increases except in two areas.
Manatee counts are highly variable without an accurate way to estimate numbers: In Florida in , a winter survey found 2, manatees; in , a January survey found 2,, and a February survey found 1, As of January , the USFWS estimates the range-wide manatee population to be at least 13,; as of January, , at least 6, are estimated to be in Florida.
Population viability studies conducted in found that decreasing adult survival and eventual extinction were a probable future outcome for Florida manatees unless they got more protection.
Fish and Wildlife Service proposed downgrading the manatee's status from endangered to threatened in January after more than 40 years of the manatee's being classified as on the endangered.
The freshwater Amazonian manatee T. They are found in coastal marine and estuarine habitats, and in freshwater river systems along the west coast of Africa from the Senegal River south to the Cuanza River in Angola.
In relation to the threat posed by humans, predation does not present a significant threat to manatees. The main causes of death for manatees are human-related issues, such as habitat destruction and human objects.
Natural causes of death include adverse temperatures, predation by crocodiles on young, [40] and disease.
Their slow-moving, curious nature, coupled with dense coastal development, has led to many violent collisions with propeller-driven boats and ships, leading frequently to maiming, disfigurement, and even death.
As a result, a large proportion of manatees exhibit spiral cutting propeller scars on their backs, usually caused by larger vessels that do not have skegs in front of the propellers like the smaller outboard and inboard-outboard recreational boats have.
They are now even identified by humans based on their scar patterns. Many manatees have been cut in two by large vessels like ships and tug boats, even in the highly populated lower St.
Johns River's narrow channels. Some are concerned that the current situation is inhumane, with upwards of 50 scars and disfigurements from vessel strikes on a single manatee.
Internal injuries stemming from being trapped between hulls and docks and impacts have also been fatal. Recent testing [ citation needed ] shows that manatees may be able to hear speed boats and other watercraft approaching, due to the frequency the boat makes.
However, a manatee may not be able to hear the approaching boats when they are performing day-to-day activities or distractions. The manatee has a tested frequency range of 8 kilohertz to 32 kilohertz.
Manatees hear on a higher frequency than would be expected for such large marine mammals. Many large boats emit very low frequencies, which confuse the manatee and explain their lack of awareness around boats.
The Lloyd's mirror effect results in low frequency propeller sounds not being discernible near the surface, where most accidents occur.
Research indicates that when a boat has a higher frequency the manatees rapidly swim away from danger. In , a population model was released by the United States Geological Survey that predicted an extremely grave situation confronting the manatee in both the Southwest and Atlantic regions where the vast majority of manatees are found.
It states,. In the absence of any new management action, that is, if boat mortality rates continue to increase at the rates observed since , the situation in the Atlantic and Southwest regions is dire, with no chance of meeting recovery criteria within years.
The severity of mutilations for some of these individuals can be astounding — including long term survivors with completely severed tails, major tail mutilations, and multiple disfiguring dorsal lacerations.
These injuries not only cause gruesome wounds, but may also impact population processes by reducing calf production and survival in wounded females — observations also speak to the likely pain and suffering endured.
Minimization of this injury is explicit in the Recovery Plan, several state statutes, and federal laws, and implicit in our society's ethical and moral standards.
In , of the Florida manatees recorded dead, 97 were killed by commercial and recreational vessels, which broke the earlier record number of 95 set in Another cause of manatee deaths are red tides , a term used for the proliferation, or "blooms", of the microscopic marine algae, Karenia brevis.
This dinoflagellate produces brevetoxins that can have toxic effects on the central nervous system of animals.
In , a red tide was responsible for manatee deaths. Manatees can also be crushed and isolated in water control structures navigation locks, floodgates , etc.
While humans are allowed to swim with manatees in one area of Florida, [51] there have been numerous charges of people harassing and disturbing the manatees.
All three species of manatee are listed by the World Conservation Union as vulnerable to extinction. However, The U. Fish and Wildlife Service FWS does not consider the West Indian manatee to be "endangered" anymore, having downgraded its status to "threatened" as of March They cite improvements to habitat conditions, population growth and reductions of threats as reasoning for the change.
The reclassification was met with controversy, with Floridan senator Vern Buchanan and groups such as the Save the Manatee Club and the Center for Biological Diversity expressing concerns that the change would have a detrimental effect on conservation efforts.
Manatee population in the United States reached a low in the 's, during which only a few hundred individuals lived in the nation.
Brazil outlawed hunting in in an effort to preserve the species. Deaths by boat strikes are still common. Born at the Miami Aquarium and Tackle Company on July 21, , Snooty was one of the first recorded captive manatee births.
Raised entirely in captivity, Snooty was never to be released into the wild. As such he was the only manatee at the aquarium, and one of only a few captive manatees in the United States that was allowed to interact with human handlers.
That made him uniquely suitable for manatee research and education. Snooty died suddenly two days after his 69th birthday, July 23, , when he was found in an underwater area only used to access plumbing for the exhibit life support system.
There are a number of manatee rehabilitation centers in the United States. After initial treatment at these facilities, the manatees are transferred to rehabilitation facilities before release.
Since , the zoo's Manatee Bay facility has helped rehabilitate 20 manatees. The River Safari at Singapore features seven of them. Since the 19th century, Georgetown, Guyana has kept West Indian manatees in its botanical garden , and later, its national park.
The manatee has been linked to folklore on mermaids. Killing one was taboo and required penance. But as these pig-fish are a noisy, contemptible set, mostly lurking in the mouths of rivers, and feeding on wet hay, and especially as they do not spout, I deny their credentials as whales; and have presented them with their passports to quit the Kingdom of Cetology.

The name mantid properly refers only to members of the family Mantidae , which was, historically, the only family in the order. The other common name, praying mantis, applied to any species in the order [8] though in Europe mainly to Mantis religiosa , comes from the typical " prayer -like" posture with folded forelimbs.
One of the earliest classifications splitting an all-inclusive Mantidae into multiple families was that proposed by Beier in , recognizing eight families, [13] though it was not until Ehrmann's reclassification into 15 families in [12] that a multiple-family classification became universally adopted.
Klass, in , studied the external male genitalia and postulated that the families Chaeteessidae and Metallyticidae diverged from the other families at an early date.
The Mantodea Species File [17] now places extant families in the suborder Eumantodea , which includes:. The earliest mantis fossils are about million years old, from Siberia.
Because of the superficially similar raptorial forelegs , mantidflies may be confused with mantises, though they are unrelated. Their similarity is an example of convergent evolution ; mantidflies do not have tegmina leathery forewings like mantises, their antennae are shorter and less thread-like, and the raptorial tibia is more muscular than that of a similar-sized mantis and bends back further in preparation for shooting out to grasp prey.
Mantises have large, triangular heads with a beak-like snout and mandibles. They have two bulbous compound eyes , three small simple eyes, and a pair of antennae.
In all species apart from the genus Mantoida , the prothorax, which bears the head and forelegs, is much longer than the other two thoracic segments.
The prothorax is also flexibly articulated, allowing for a wide range of movements of the head and fore limbs while the remainder of the body remains more or less immobile.
Most mantids can only hear ultrasound. Mantises have two spiked, grasping forelegs "raptorial legs" in which prey items are caught and held securely.
In most insect legs, including the posterior four legs of a mantis, the coxa and trochanter combine as an inconspicuous base of the leg; in the raptorial legs, however, the coxa and trochanter combine to form a segment about as long as the femur , which is a spiky part of the grasping apparatus see illustration.
Located at the base of the femur is a set of discoidal spines, usually four in number, but ranging from none to as many as five depending on the species.
These spines are preceded by a number of tooth-like tubercles, which, along with a similar series of tubercles along the tibia and the apical claw near its tip, give the foreleg of the mantis its grasp on its prey.
The foreleg ends in a delicate tarsus used as a walking appendage, made of four or five segments and ending in a two-toed claw with no arolium.
Mantises can be loosely categorized as being macropterous long-winged , brachypterous short-winged , micropterous vestigial-winged , or apterous wingless.
If not wingless, a mantis has two sets of wings: the outer wings, or tegmina , are usually narrow and leathery. They function as camouflage and as a shield for the hindwings, which are clearer and more delicate.
The abdomen tends to be slimmer in males than females, but ends in a pair of cerci in both sexes. Mantises have stereo vision.
A small area at the front called the fovea has greater visual acuity than the rest of the eye, and can produce the high resolution necessary to examine potential prey.
The peripheral ommatidia are concerned with perceiving motion; when a moving object is noticed, the head is rapidly rotated to bring the object into the visual field of the fovea.
Further motions of the prey are then tracked by movements of the mantis's head so as to keep the image centered on the fovea.
This occurs because the ommatidia that are viewed "head-on" absorb the incident light , while those to the side reflect it. As their hunting relies heavily on vision, mantises are primarily diurnal.
Many species, however, fly at night, and then may be attracted to artificial lights. Mantises in the family Liturgusidae collected at night have been shown to be predominately males; [31] this is probably true for most mantises.
Nocturnal flight is especially important to males in locating less-mobile females by detecting their pheromones.
Flying at night exposes mantises to fewer bird predators than diurnal flight would. Many mantises also have an auditory thoracic organ that helps them avoid bats by detecting their echolocation calls and responding evasively.
Mantises are generalist predators of arthropods. They either camouflage themselves and remain stationary, waiting for prey to approach, or stalk their prey with slow, stealthy movements.
Larger mantises sometimes eat smaller individuals of their own species, [35] as well as small vertebrates such as lizards, frogs, fish, and particularly small birds.
Most mantises stalk tempting prey if it strays close enough, and will go further when they are especially hungry.
For example, members of a few genera such as the ground mantises, Entella , Ligaria , and Ligariella run over dry ground seeking prey, much as tiger beetles do.
The fore gut of some species extends the whole length of the insect and can be used to store prey for digestion later. This may be advantageous in an insect that feeds intermittently.
Mantises are preyed on by vertebrates such as frogs, lizards, and birds, and by invertebrates such as spiders, large species of hornets , and ants.
When directly threatened, many mantis species stand tall and spread their forelegs, with their wings fanning out wide. The fanning of the wings makes the mantis seem larger and more threatening, with some species enhancing this effect with bright colors and patterns on their hindwings and inner surfaces of their front legs.
If harassment persists, a mantis may strike with its forelegs and attempt to pinch or bite. As part of the bluffing deimatic threat display , some species may also produce a hissing sound by expelling air from the abdominal spiracles.
Mantises lack chemical protection, so their displays are largely bluff. When flying at night, at least some mantises are able to detect the echolocation sounds produced by bats; when the frequency begins to increase rapidly, indicating an approaching bat, they stop flying horizontally and begin a descending spiral toward the safety of the ground, often preceded by an aerial loop or spin.
If caught, they may slash captors with their raptorial legs. Mantises, like stick insects , show rocking behavior in which the insect makes rhythmic, repetitive side-to-side movements.
Functions proposed for this behavior include the enhancement of crypsis by means of the resemblance to vegetation moving in the wind. However, the repetitive swaying movements may be most important in allowing the insects to discriminate objects from the background by their relative movement, a visual mechanism typical of animals with simpler sight systems.
Rocking movements by these generally sedentary insects may replace flying or running as a source of relative motion of objects in the visual field.
Exploiting this behavior, a variety of arthropods, including some early-instar mantises, mimic ants to evade their predators. Leaf mimicry : Choeradodis has leaf-like forewings and a widened green thorax.
Adult female Iris oratoria performs a bluffing threat display , rearing back with the forelegs and wings spread and mouth opened.
The jeweled flower mantis, Creobroter gemmatus : the brightly colored wings are opened suddenly in a deimatic display to startle predators.
Some mantis nymphs mimic ants to avoid predators. The mating season in temperate climates typically takes place in autumn, [55] [56] while in tropical areas, mating can occur at any time of the year.
He then arches his abdomen to deposit and store sperm in a special chamber near the tip of the female's abdomen.
The female lays between 10 and eggs, depending on the species. Eggs are typically deposited in a froth mass-produced by glands in the abdomen. This froth hardens, creating a protective capsule, which together with the egg mass is called an ootheca.
Depending on the species, the ootheca can be attached to a flat surface, wrapped around a plant, or even deposited in the ground.
In a few species, mostly ground and bark mantises in the family Tarachodidae , the mother guards the eggs. As in closely related insect groups in the superorder Dictyoptera, mantises go through three life stages: egg, nymph, and adult mantises are among the hemimetabolous insects.
For smaller species, the eggs may hatch in 3—4 weeks as opposed to 4—6 weeks for larger species. The nymphs may be colored differently from the adult, and the early stages are often mimics of ants.
A mantis nymph grows bigger as it molts its exoskeleton. Molting can happen five to 10 times before the adult stage is reached, depending on the species.
After the final molt, most species have wings, though some species remain wingless or brachypterous "short-winged" , particularly in the female sex.
The lifespan of a mantis depends on the species; smaller ones may live 4—8 weeks, while larger species may live 4—6 months.

Sexual cannibalism is common among most predatory species of mantises in captivity. It has sometimes been observed in natural populations, where about a quarter of male-female encounters result in the male being eaten by the female.
The female may begin feeding by biting off the male's head as they do with regular prey , and if mating has begun, the male's movements may become even more vigorous in its delivery of sperm.
Early researchers thought that because copulatory movement is controlled by a ganglion in the abdomen, not the head, removal of the male's head was a reproductive strategy by females to enhance fertilization while obtaining sustenance.
Later, this behavior appeared to be an artifact of intrusive laboratory observation. Whether the behavior is natural in the field or also the result of distractions caused by the human observer remains controversial.
Mantises are highly visual organisms and notice any disturbance in the laboratory or field, such as bright lights or moving scientists.
Chinese mantises that had been fed ad libitum so that they were not hungry actually displayed elaborate courtship behavior when left undisturbed.
The male engages the female in a courtship dance, to change her interest from feeding to mating. The reason for sexual cannibalism has been debated; experiments show that females on poor diets are likelier to engage in sexual cannibalism than those on good diets.
This is contrasted by a study where males were seen to approach hungry females with more caution, and were shown to remain mounted on hungry females for a longer time, indicating that males that actively avoid cannibalism may mate with multiple females.
The same study also found that hungry females generally attracted fewer males than those that were well fed.
An increase in mounting duration appears to indicate that males wait for an opportune time to dismount a hungry female, who would be likely to cannibalize her mate.
One of the earliest mantis references is in the ancient Chinese dictionary Erya , which gives its attributes in poetry, where it represents courage and fearlessness, and a brief description.
A later text, the Jingshi Zhenglei Daguan Bencao "Great History of Medical Material Annotated and Arranged by Types, Based upon the Classics and Historical Works" from , gives accurate details of the construction of the egg packages, the development cycle, anatomy, and the function of the antennae.
Although mantises are rarely mentioned in Ancient Greek sources, a female mantis in threat posture is accurately illustrated on a series of fifth-century BC silver coins, including didrachms , from Metapontum in Lucania.
Western descriptions of the biology and morphology of the mantises became more accurate in the 18th century. Roesel von Rosenhof illustrated and described mantises and their cannibalistic behavior in the Insekten-Belustigungen Insect Entertainments.
Aldous Huxley made philosophical observations about the nature of death while two mantises mated in the sight of two characters in his novel Island the species was Gongylus gongylodes.
The naturalist Gerald Durrell 's humorously autobiographical book My Family and Other Animals includes a four-page account of an almost evenly matched battle between a mantis and a gecko.
Cicely [the mantis] retaliated by snapping both her front legs shut on Geronimo's hindlegs. They rustled and staggered across the ceiling and down the wall, each seeking to gain some advantage.
Escher 's woodcut Dream depicts a human-sized mantis standing on a sleeping bishop. In the film Son of Godzilla and other related films, the kaiju called " Kamacuras " are giant mantis monsters.
A cultural trope imagines the female mantis as a femme fatale. McCracken, and Mark Parisi, among others.
Two martial arts separately developed in China have movements and fighting strategies based on those of the mantis. The mantis was revered by the southern African Khoi and San in whose cultures man and nature were intertwined; for its praying posture, the mantis was even named Hottentotsgot "god of the Khoi" in the Afrikaans language that had developed among the first European settlers.
Mantises are among the insects most widely kept as pets. In at least 31 species were kept and bred in the United Kingdom, the Netherlands, and the United States.
Gardeners who prefer to avoid pesticides may encourage mantises in the hope of controlling insect pests. Two species, the Chinese mantis and the European mantis, were deliberately introduced to North America in the hope that they would serve as pest controls for agriculture; they have spread widely in both the United States and Canada.
A prototype robot inspired by the forelegs of the praying mantis has front legs that allow the robot to walk , climb steps, and grasp objects.
The multi-jointed leg provides dexterity via a rotatable joint. Future models may include a more spiked foreleg to improve the grip and ability to support more weight.
