What adaptations help a crocodile catch their prey?
What might be an advantage to darker coloration for an alligator?
The species of crocodile that change colors revealed some information about when this ability likely evolved. However, adults would benefit from dynamic coloration, as hiding from prey would aid in the ambush-style hunting crocodiles typically rely on.
How do crocodiles protect themselves?
Crocodilians (crocodiles and alligators) have powerful senses that they can use to hunt and protect themselves. They have exceptional hearing that helps to warn them.
