Cutest sea creatures

After I looked at which marine animals give me goosebumps , it is time to explore the opposite. Let's check out the cuties of the oceans: 1) Dumbo octopus (Grimpoteuthis): Apart from Dumbo being one of my favorite cartoons ever, this octopus is nothing short of beautiful.

Ocean Quotes 5: John F. Kennedy

Great words from a greater man: "And it is an interesting biological fact that all of us have, in our veins the exact same percentage of salt in our blood that exists in the ocean, and, therefore, we have salt in our blood, in our sweat, in our tears.
