These little creatures are flipping gender roles on their head. They are the only species in which the male is solely responsible for birthing and caring for their young.

9. Clownfish

Although sea anemone’s produce a toxin that can kill other marine life, clownfish have developed an immunity to the toxin and use the anemone for protection from predators.

8. Sea Turtles

Sea turtles are clearly creatures of habit. Female sea turtles return to the same beach every year to lay their eggs.

7. Sea Otters

Sea otters are some of the cutest sea animals around. They like to play and swim, and they even hold hands while they sleep so they don’t drift apart. One interesting fact about these animals is that they have a built in pocket of skin under their arms to store food.

The parrotfish has developed an amazing self-defense mechanism. When they sleep, they surround themselves with a bubble of mucous to prevent predators from picking up on their scent.

These stunning sea creatures have many impressive traits. Penguin proposals must be so adorable, and they are always “dressed” for the occasion and clownfish becoming “friends” with a dangerous anemone is very cool. The world’s oceans are filled with amazing and fascinating creatures.
