Large shallow inlets and bays
The corkwing wrasse, Symphodus melops, has been observed to feed extensively on the genital pinnules of Antedon bifida (Fish & Fish, 1996) and pieces of Antedon bifida were found in the stomach of Galathea strigosa (Nickell & Sayer, 1998). Antedon bifida may lose up to half their pinnules through predation, largely, if not entirely by the corkwing wrasse (Nichols, 1994).
