The Japanese Spider Crab
This crab gets its name honestly. The Japanese Spider Crab can be found in Japan, yet it has also managed to show up in other areas of Asia. Of course, they are incredibly unique. Due to that, you can find them in many aquariums all over the world too. You’d be forgiven for being thrown back a bit by their appearance. While this truly is a crab, the spider-like features make it much scarier. Worst of all, these creatures get to quite a large size too.
