Many different species of Ichthyosaur are now known. As a group, they were perhaps the best adapted to a life in the water of all the marine reptiles.

How do marine reptiles reproduce?

How does temperature affect the marine reptile nesting?
Females need warmer temperatures in order to develop. For example, in green turtles, temperatures need to be 88 F or above for the eggs to become females. Climate change may also affect the nesting grounds of turtles if sea levels rise. Beaches currently being used by turtles may vanish under the sea.
