General Biology Additional Information
  • Growth rate: Growth in Echinocardium cordatum is particularly rapid during the first and second years of life. There are also seasonal variations that are characterised by an alternation of slow and rapid growth rates, with rapid growth during spring and summer months (Ridder de et al., 1991).
  • The bivalve Tellimya (=Montacuta) ferruginosa is a commensal of Echinocardium cordatum, and as many as 14 or more of this bivalve have been recorded with a single echinoderm. Adult specimens live freely in the burrow of Echinocardium cordatum, while the young are attached to the spines of the echinoderm by byssus threads (Fish & Fish, 1996). The amphipod crustacean Urothöe marina (Bate) is another common commensal (Hayward & Ryland, 1995).
