Biology of the king crab Paralomis birsteini on the continental slope off the western Antarctic Peninsula
Predatory king crabs (Lithodidae) structure benthic communities in their native habitats and cause shifts in the composition of benthic assemblages when introduced to new environments. Cold temperatures have apparently excluded skeleton-breaking predators from the continental shelf around Antarctica...
