Challenging the cold: Crabs reconquer the antarctic
Abstract. Recent records of lithodid crabs in deeper waters off the Antarctic continentalslope raised the question of the return of crabs to Antarctic waters, following their extinctionin the lower Miocene ;15 million years ago. Antarctic cooling may be responsible for theimpoverishment of the marin...
