Mantis shrimp

Though their name suggests otherwise, mantis shrimp are not shrimp nor mantids. They often come in a variety of beautiful colors and are known for their powerful claws, which have been known to break through aquarium glass with a single strike.

Known for their feisty dispositions, mantis shrimp are bad news for any prawn that swims past, but they do have a softer side. Some mantis shrimp form monogamous pair bonds and stay together for as long as 20 years. They also have some of the most advanced eyes in the animal kingdom.
