Where the name comes from

Terrapene comes from torope, the word the Algonquian peoples of the Atlantic coast used for freshwater turtles; from the same root comes the English terrapin. Carolina names the colonies where it was described. The common name comes from the plastron, which has two hinges and closes completely: the animal turns into a sealed box.

Characteristics

  • 01

    Shut inside its shell it is impenetrable even to a raccoon.

  • 02

    It eats fungi that are poisonous to people without any harm.

  • 03

    It lives its whole life in a patch of wood a few hundred metres across.

What sets it apart

It spends its entire life in a territory the size of a couple of football pitches and knows it by heart: moved elsewhere, it walks in a straight line towards home for kilometres if need be, and in doing so it crosses roads. That is why it is disappearing — an animal that lives a hundred years and lays few eggs cannot absorb a steady road death toll, and the species is going extinct slowly, without anyone hunting it.
