TGIF: Is the Dead Man's Crab The Largest


At 00:48, video of the Japanese Spider Crab, or the Dead Man’s Crab*, occurs and touted as the world’s largest. But is it? Sure its big with a leg span that can reach several meters but it is all leg. Weight or mass wise, I would argue that the world’s largest crab and modern arthropod is the Tasmanian Giant Crab.

*Called because its been seen scavenging on the bodies of the drowned

  1. Great pics, but pity about the vapid commentary. The cusk looked like Spectrunculus grandis, but I thought the deepest living ophidid was Abyssobrotula galatheae (8,370m cf. 4,255m)
