Behaviour of Brahminy River Turtle
The reproductive habits of Brahminy River Turtle are unique among reptiles of Indian biosphere reserves in that the female Brahminy River Turtle or Crowned River Turtle lay their eggs under water rather than on dry land. The reproductive cycle of Brahminy River Turtle or Crowned River Turtle follows seasonal changes in the water levels of the rivers in which they live.
Laying of Eggs by Female Brahminy River Turtle
In autumn, the female Brahminy River Turtle lays eggs under water, where higher water levels submerge the eggs for 40 to 45 days. During winter, lower water levels expose the eggs for five months. The rising water levels of spring submerge the almost mature eggs once again, and the turtles hatch in the river.
