Peacock mantis shrimp Say hello to the peacock mantis shrimp. His bright colors might be beautiful to behold, but don't get too close. His hammer-like claws are powerful enough to break a human finger, which is why the species has been dubbed "thumb-splitter" by fishermen in the Indo-Pacific ocean, where the crustaceans live.

The color is determined by the creatures' individual DNA. (WTOP/Alicia Lozano)

Goliath bird-eating tarantula The Goliath bird-eating tarantula doesn't actually eat birds, but was so named because of its giant size. They can grow to be about the size of a dinner plate. This particular spider is about 3 to 4 years old, and is currently starving itself so it can wriggle out of its current skin and into a new one. Its bite is not lethal to humans, but the venom can cause severe pain, nausea and sweating. (WTOP/Alicia Lozano)
