Very large turtle; shell is up to 20 inches long (about the length of an arm?)
They can live nearly 50 years in captivity.
Pair of sharp and very strong jaws. They can give a nasty bite so don't try to pick one up. Could easily amputate a finger with one bite. No teeth - just a jagged mouth.
Highly mobile neck - can turn 180 degrees but they cannot pull their head into the shell, so they snap as a defense instead.
May travel several hundred yards from water to nesting site during the spring.
Has a “worm-like” appendage in its mouth that attracts fish when held open underwater.
They are omnivores.
