Paralomis spinosissima, also known as the Antarctic stone crab,[2] is a species of king crab.[1][3] It has been found in the Southeast Atlantic, the Scotia Sea, near South Georgia island, and south of the Falkland Islands at depths of 132–877 m (433–2,877 ft).[4] It thrives at temperatures of about 1 °C (34 °F), relatively low for king crabs.[5]

Description

[edit]

Paralomis spinosissima's carapace is pyriform or nearly pentagonal and is slightly longer than it is wide.[4] Its rostrum extends past the eyestalks and consists of three sharp spines – one medial pointing forward and two dorsal diverging outward and upward.[4] Its carapace is covered with long, conical spines, and its walking legs and chelipeds are densely covered in long, sharp ones.[4] The lateral and posterior regions of the carapace are covered by small spines, while the dorsal and ventral margins are covered in tall spines and blunt spines, respectively.[4] It can grow up to 126 mm (5.0 in) in length and 132 mm (5.2 in) in width, and adults have weighed up to 1.40 kg (3.1 lb).[6]
