Defenses

With the exception of "apex" predators such as orcas and great white sharks, every animal living in the sea is subject to predation. Potential prey have evolved a myriad of defensive strategies and most animals employ more than one of these. There are simple tactics such as swimming away or hiding, and more complex ones that include the use sharp spines, toxic chemicals or venom. There are even animals that mimic the appearance of a different animal that has an effective defense such as venom, while not actually possessing it themselves.
