5. Whitetip reef

The whitetip reef shark reminds me a bit of dogs and cats that have white “socks” on their feet. (Of course, in lieu of feet this fish had to decorate its fin). Unlike sharks such as the sand tiger shark, whitetip reef sharks are communal creatures and often lie on top of each other in the same home cave, sometimes for weeks at a time. Who doesn’t like hanging out with friends?
