The clownfish
Have you ever seen the animated Disney movie Finding Nemo, in which a small, brightly-colored fish starts off a relentless search for his son? If so, then you’re probably familiar with the marine animal we’ll discuss next: the clownfish.

Extremely shy yet visually striking, clownfish are commonly found in coral reefs, especially inside anemones. These animals are aggressively territorial of their homes and would do anything to keep prying fish from eating their anemone’s tentacles.
