Where the name comes from

Chelus is the Greeks’ lyre-tortoise; fimbriata means “fringed”, for the flaps of skin hanging from its neck and head like torn weed. Matamata is a word from the Carib languages of Guiana, and the name is odd enough to have entered every European language exactly as it stands.

Characteristics

  • 01

    It looks like a rotting leaf among other rotting leaves.

  • 02

    It has a long neck and a snout drawn out into a little tube for breathing.

  • 03

    It neither chews nor bites: it has practically no teeth.

What sets it apart

It does not hunt: it inhales. When a fish passes in front of it the turtle snaps its mouth open and expands its throat, and the pressure drop sucks in water and prey in a fiftieth of a second — too fast for the human eye without slow motion. Then it closes, lets the water out at the sides and swallows. Everything else about the animal — the fringes, the lumpy shell, the hours of stillness — exists only to make sure that fish comes past.
