Northern River Terrapin

Batagur baska

Critically Endangered

Spotted something wrong?

In the breeding season the males take on spectacular colours: the head turns black and the neck an intense red, a change that is highly unusual among turtles.

Fun facts

  • The males change colour to breed: the head turns black and the neck an intense scarlet for a few weeks, a seasonal dimorphism that almost no other turtle shows.
  • It was given up for extinct in several South-East Asian countries before remnant populations were found in temples and ponds, where they had lived for decades without anyone identifying the species.
  • Fewer than a hundred known breeding females remain in the world, and practically the whole recovery programme depends on a few breeding centres in India and Bangladesh.
