Giant snapping turtle

A giant snapping turtle was, as the name suggested, a huge-sized variety of snapping turtle.

Description
Giant snapping turtles resembled regular snapping turtles in all respects, only much bigger, growing to diameters of up to. Like normal turtles, they had a bony outer shell, divided into an upper half called a carapace and a lower half called a plastron. They were capable of withdrawing their more lightly armored head and legs partly or wholly into this shell for defense, but their heads could extend up to long in the very largest specimens. Although they typically moved and swam slowly, they were capable of shocking speed when they attacked.

Abilities
Giant snapping turtles were amphibious.

Behavior
Known to be aggressive and ravenous in appetite, they were rightly feared for the danger they posed. They would snap at smaller creatures that came close.

Combat
Giant snapping turtles hunted by lying still at the bottom of a lake or river or close to shore, before they swiftly extended their necks to snatch their surprised prey, inflicting grievous injury —one could well bite a human in half. If the victim was grabbed and still lived, the giant snapping turtle kept biting, and it took a great feat of strength to free oneself. When the prey was subdued or slain, the giant snapping turtle threw its head back, tossed the prey a few feet in the air, then caught and swallowed it.

When attacked, the giant snapping turtle was too slow to flee or put up a fight, so it preferred to withdraw into its shell, which granted great protection. While some breeds were unable fully withdraw, they tucked their limbs against the shell to minimize exposure. They would then deliver deadly bites against the attackers. Their builds made them very stable, but when they were knocked on their backs, it took an effort to right themselves.

Ecology
Giant snapping turtles were omnivorous creatures, taking whatever they found in their environment, from all kinds of insects and fishes to plants and small mammals, and even humans. They had a preference for fresh green plants and live worms, and understandably avoided carrion or rotting plant matter except when starving.

While it varied with species, giant snapping turtles lived a long time, anywhere for thirty years to a hundred and fifty years.

They were encountered alone.

Habitats
Giant snapping turtles dwelled in large freshwater lakes and rivers. Being uncommon but not rare, sightings of them were possibly the origins of some stories of lake monsters. It was possible that a desert-adapted giant snapping turtle might even exist.

Uses
Many cultures considered giant turtle meat a delicacy; it was tasty and nutritious.

The carapaces of giant turtles could be used to make sturdy roofs, small huts, and boats.
