Puffer fish have adapted structurally to the threat of predators by developing an elastic stomach which allows them to inflate and momentarily appear larger
They have adopted physiologically by posessing a potent neurotoxin in their internal organs.
Many scientists believe that whales are more closely related to land mammals than other sea dwelling creatures because they share homologous structures like their similar skeletal systems (including the vestigial pelvis) and their blowhole, which is homologous to a mammalian nostril..
Although whales and sharks have many similarities, like their pointed teeth, these similarities are considered to ba analogous because they do not orginiate from a common ancestor.
The angler fish uses its lure, which mimics a small fish, to attract prey.
Cuttl;efish can change the color and texture of their skin at will in order to blend in with their environment.
