What Are the Predators for Snapping Turtles? | Sciencing
Apr 24, Snapping turtles are highly aquatic, omnivorous turtles that inhabit fresh Many animals eat turtle eggs and hatchlings, including raccoons. Like all turtles, snapping turtles have a shell that covers their back, also and legs into their shell for protection against predators, as most other turtles can. These animals are found in the following types of habitat; temperate; freshwater. The alligator snapping turtle (Macrochelys temminckii) is a species of turtle in the family Alligator snapping turtle using its vermiform appendage to lure prey. ( Peckham's .. "A study of bite force, part 2: Relationship to various cephalometric .
The shell of the turtle often has algae growing on it that help the animal to camouflage itself in the wild. Feeding Habits The alligator snapping turtle is an omnivore that consumes both meat and plants although it prefers invertebrates and fish more often. It is an opportunistic feeder that relies on both living foods as well as dead organisms which it can scavenge.
In general, the species eat almost anything they can get their hands on. The alligator snapping turtle generally prefers to catch prey, like for example fish, that is abundant and easy to prey on. Their diet primarily consists of fish and fish carcasses, mollusks, carrion, crustaceans and amphibians. They are also known to prey on snakes, crayfish, worms, aquatic plants, water birds and other turtles. The snapper uses its tongue to lure prey near enough for a strike.

During the day they lie quietly at the bottom of murky water keeping their jaws open and waiting for their prey. The tongue is wriggled to mimic the movements of a worm that generally attracts fish and several invertebrates towards the predator. Young alligator snappers use this technique to catch small fish like minnows. Adults, however, must forage more actively to satisfy their voracious appetites.

Another regular food source for alligator snappers are plants like nuts, seeds, wood, bark, roots, leaves or stems. Predator Alligator snapping turtles are large enough to be considered major predators in the wild. However, despite their size and rocky built, also this species face certain threats, especially from humans. Hatchlings are often preyed on by raccoons, predatory fish, large birds and freshwater alligators. Humans find the alligator snapping turtle quite valuable for its meat and appearance.
As a consequence, illegal trade and hunting are common problems for this species. Reproduction The mating season for Alligator snapping turtles begins in early spring in the southern part of the continent like Florida and late spring in northern ends like Mississippi Valley. The species is polygynandrous which means both male and female snappers mate with more than one partner. The breeding is seasonal and it takes place once a year.
The species reaches sexual maturity within 11 — 13 years. During the breeding season, Alligator snappers are quite territorial and upon finding a potential female mate, they mount the back of the female as a form of showing their approval.
They grasp the shell of the female snapper using their sharp, crooked feet to induce insemination.
The fertilization is oviparous where the female lays eggs in a nest, which is a dug hole approximately 50 m from a water source. The nest is dug in the sand and the clutch size depends upon various factors.
A clutch may contain as many as 8 — 52 eggs and incubation generally persists for — days. Hatchlings tend to be born in the fall and are independent at birth which is also why they often become easy prey for vicious predators.
The sexual orientation of the newborn depends on the incubation temperature. The newborn alligator snappers are very similar to adults in terms of their appearance. Where females generally are born if the incubation temperature is around 29 — 30 degree Celsius, males are born when a lower incubation temperature condition of 25 — 27 degree Celsius has existed.
Baby alligator snapper turtles feed on snails, guppies, tadpoles, crayfish and other small invertebrates in the water. However, today all three have been differentiated into three separate species. They are the largest freshwater turtles found in North American waters that spend most of their time in the water and generally only come out to bask in the sun. They are solitary creatures that show little to less parental care.
While adult alligator snappers reside in rivers, swamps and canals, the hatchlings stay near small streams. The most distinguishing feature of the species is the presence of three dorsal ridges of large scales on the shell that give it a prehistoric appearance. With radiating yellow patterns around the eyes and algal growth on the carapace, the species gets naturally camouflaged in the wild. Radiated eye pattern of the Alligator Snapping Turtle?
A fascinating adaptation of the Alligator snapper is its tongue that is shaped like a worm which it wriggles to attract prey. The Macrochelys temminckii is a bottom feeder that is mostly active at night and is known to feed often on decaying remains.

Alligator snappers generally eat all year round. However, they refuse to eat when the temperature is high and therefore prefers a warm winter season to search for food in water and along the shoreline. The species shows seasonal migration where a few populations are known to make extended movements at particular times of the year for finding hibernation sites and breeding grounds.
Even though they migrate on a local base, older individuals generally move upstream as years pass by. The species is quite aggressive when defending itself and shows very little social interaction. The Snapping turtle is quite aggressive when defending itself? If attacked or picked up the snapper will shoot its head forward with incredible speed and will use its enormous jaw to bite.
It extends its neck forward and closes its jaws with a loud crunch grabbing onto its attacker with a bite force that can easily deliver a painful wound.

Sometimes the species also likes to bury themselves in the mud with only its nostrils and eyes exposed, which is another adaptation to catch prey. A mature male's cloaca extends beyond the carapace edge, a female's is placed exactly on the edge if not nearer to the plastron. The base of the tail of the male is also thicker as compared to females because of the hidden reproductive organs.
The inside of the turtle's mouth is camouflaged, and it possesses a vermiform i. The turtle hunts by lying motionless in the water with its mouth wide open. The vermiform tongue imitates the movements of a worm, luring prey to the turtle's mouth. The mouth is then closed with tremendous speed and force, completing the ambush. They rely on both live food caught by themselves and dead organisms which they scavenge. In general, they will eat almost anything they can catch. Fishermen have glorified the species' ability to catch fish and to deplete fish populations, whereas in fact they largely target any abundant and easily caught prey, and rarely have any extensive deleterious effect on fish populations.
They may also hunt diurnally, however. By day, they may try to attract fish and other prey by sitting quietly at the bottom of murky water and let their jaws hang open to reveal their tongues, which look like small, pink, worm-like lures in the back of their gray mouths, and lure the prey into striking distance.
They will refuse to eat if exposed to extreme temperatures.
The female builds a nest and lays a clutch of 10—50 eggs  about two months later. The sex of the young depends on the temperature at which the eggs are incubated. Nests are typically excavated at least 50 yards from the water's edge to prevent them from being flooded and drowned. Incubation takes from to days, and hatchlings emerge in the early fall. Due to their potential size and specific needs, they do not make particularly good pets for any but the most experienced aquatic turtle keepers.
Hand feeding is dangerous.
