General Biology Additional Information	Densities vary from solitary individuals to dense carpets in ideal locations such as crevices and gullies. Measurements of size refer to the diameter across the base. Growth is dependent on the level of feeding so size is not proportional to age. Gosse (1860) notes [most likely from aquarium observations] that "the shore crab (Carcinus) is its ordinary prey but it feeds on limpets, and other Mollusca and nereids and shrimps and on Echinus [now Psammechinus] miliaris. Rasmussen (1973) records Urticina felina as feeding mainly on gammarids in banks of Mytilus edulis.
