Where the name comes from

Macrochelys is “big turtle”, from makrós and chélys, the Greek word that meant both the tortoise and the lyre — because the first lyres were made by stringing cords across an empty shell. Temminckii recalls Coenraad Temminck, director of the Leiden museum. The common name comes from the three saw-toothed ridges of the shell, which recall an alligator’s back.

Characteristics

  • 01

    It is the heaviest freshwater turtle in North America.

  • 02

    It lies motionless on the bottom for forty minutes between breaths.

  • 03

    The shell is covered in algae that make it indistinguishable from a stone.

What sets it apart

It fishes with bait. On the floor of its mouth sits a pink appendage it can engorge and wriggle, which to a fish looks in every way like a worm: the turtle lies still with its jaws wide, works the false worm, and snaps shut when somebody comes for it. It is one of very few non-human vertebrates to use a lure of the kind, and the only reptile in North America that does.
