Necora puber, also known as the velvet swimming crab, may not be as soft as the name implies. The crab's red eyes and aggressive nature have resulted in a second nickname, devil's crab. As if it weren’t intimidating enough already, Necora puber is also the largest swimming crab found off of Britain’s coast. However not everyone is scared. Scotland has increased the capture of the red-eyed crab after the decline of the Spanish fishery in the 1980s. However this could be threatened due to acidification causing problems with the exoskeleton.
