Boxer Crab
The boxer crab earns its moniker whenever it feels like it is being attacked. The sea creature uses sea anemones, sponges, or corals like a pair of boxing gloves to keep enemies from getting too close.
This relationship between boxer crabs and sea anemones is one of the most unusual in all of nature. The anemones get a free ride across the ocean on the crabs’ claws, and in return, they assist the crabs in warning the predators and packing a punch with its stinging cells.
