General Biology Additional Information	Size range and size at maturity: values given are for Mediterranean individuals (Muino et al., 1999). Feeding: Swimming crabs may exploit a wide range of dietary items including algae, sponges and many small invertebrates and may be considered omnivorous. However, Liocarcinus depurator is typically a scavenger and a carnivore. Freire et al. (1996) suggest the high diversity of food items in the diet of Liocarcinus depurator is due to the versatile functional structure of the chelipeds. Host for: Abelló et al., (1988) found 5% of individuals in the northwestern Mediterranean infested with the polychaete Iphitime cuenoti. No evidence of disease in the branchial chamber was found and the authors suggest a commensal relationship between the crab and the polychaete. However, the relationship may involve some degree of parasitism. In the Firth of Lorne the parasitic nemertean Carcinonemertes carcinophila was found the gills of over 90% of Liocarcinus depurator sampled (Comely & Ansell, 1989(b)).
