Often weighing as much as 19 kg, the Japanese Spider Crab is a gigantic crab. The species are known to possess the greatest leg span of any arthropod and has claws that are powerful enough to inflict serious injuries to the average adult. Though, despite how threatening the crab is, it’s usually rather gentle and rarely attacks humans. And no, it’s not a Pokemon. (Sorry guys!!)
