9. Blue Whale

This is the largest mammal on the planet, it can dive to depths we can’t even imagine, and it sings like something out of some creepy Spielbergien alien movie. On top of all that awesome stuff you get to have epic sea battles with obsessed bearded sea captains and mythical beasts like the giant squid. This is the most under appreciated animal on the planet, for sure.
