The species is wide-ranging, found in the north-eastern Atlantic Ocean and the Mediterranean Sea.The pale- to dark-green female, with a 15 cm-long, round or sausage-shaped body, lives on the sea-floor at a depth of 10 to 100 metres, concealed by burrowing in gravel or hiding in rock crevasses or burrows abandoned by other animals. It has two anchoring hooks underneath its body and an extensible feeding proboscis up to 10 times its body-length. It is mainly a detritivore, feeding also on small animals. The male is rarely observed: it has a flat, unpigmented body which grows to only 1–3 mm, taken up mostly by reproductive organs and devoid of other structures; it lives on or inside the body of a female.
