Podding of juvenile king crabs Lithodes santolla (Molina, 1782) (Crustacea) in association with holdfasts of Macrocystis pyrifera (Linnaeus) C. Agardh, 1980

Underwater photographic records and sampling were carried out in Steamer Bay, Strait of Magellan, Chile, to study the spatial distribution patterns of juvenile king crabs Lithodes santolla during late winter and early spring in 2006. Observations were made on the relationship between these crabs and...

Observations were made on the relationship between these crabs and the holdfasts and stipes of the large kelp Macrocystis pyrifera. Dense aggregations, known as pods, of juvenile king crab (34-75 mm CL) were observed and photographed for the first time in specific areas of the embayment in relation to Macrocystis; pod abundance varied between 2 and 70 ind·m-2.
