The Common edible crab and parasitic barnacle seen above was found by Rob Durrant, on the lowershore at Lee Bay, near Ilfracombe, North Devon. 18.09.16.

The specimen was fixed in 100% ethanol and dissected a few days after finding. The barnacle appears to contain an egg mass. I am not sure if this is the egg mass of a female barnacle or of a parasite of the parasite.

Identification of this species is based on the paper Diseases of the European edible crab (Cancer pagurus): a review. – ICES Journal of Marine Science, 65: 1578–1592. Grant D. Stentiford of the European Community Reference Laboratory for Crustacean Diseases, Centre for Environment, Fisheries and Aquaculture Science, Weymouth, Dorset, England.

Sacculina triangularis is now a synonym of Sacculina inflata, ref. WoRMS.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help
people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
