Crocodiles have developed behaviors to control their body thermostat: they bask in the sun when cool and seek shade or water when hot. Ectotherms like crocs don’t need to eat regularly to warm their bodies, and so they save an enormous amount of energy that can be put to other use or stored for later.Sep 15, 2011[1]

How Do Alligators Adapt To Their Habitat?

Do Saltwater Crocodiles Ever Stop Growing?
For starters, it’s a myth that crocs and gators never stop growing. ‘No, crocodiles don’t grow indefinitely, prevented from exceeding the size of a small moon only because they get killed first by a competitor!’ croc researcher Adam Britton told me.[19]
