Calappa (crab)

Calappa is a genus of crabs known commonly as box crabs or shame-faced crabs. The name box crab comes from their distinctly bulky carapace, and the name shame-faced is from anthropomorphising the way the crab's chelae (claws) fold up and cover its face, as if it were hiding its face in shame.[2]

gollark: Ah, they called them "visual compute accelerators" or something.
gollark: It's not "extra cores". It's basically a separate device.
gollark: I don't know why.
