Podding of Paralomis granulosa (Lithodidae) juveniles inhabiting kelp forests of the Cape Horn Archipelago (Chile)
Abstract Subtidal observations along the Cape Horn Archipelago, Chile (CHA) in February 2017 revealed an unusually large aggregation (or pod) of juvenile false king crabs, Paralomis granulosa (Hombron and Jacquinot, 1846), in association with kelp forests (Macrocystis pyrifera and Lessonia spp.).
