Description

Echinocardium flavescens is about 5 cm (2.0 in) long. It is yellow to the tube feet (hence the name flavescens, "yellowish")[4] and has spines on the underside of the body. The frontal ambulacrum is not indented and there are larger spines in the interambulacral areas of the upper side of the test. Its labrum is long, reaching the second pair of ambulacral plates.[5]

Distribution

Found in the waters off Great Britain, Ireland and associated islands.[6]

Biology

Matures in early summer.[7]

Ecology

Echinocardium flavescens buries itself about 4 in (100 mm) deep in coarse gravel in the sublittoral,[8] up to depths of 200 m (660 ft),[7] sometimes associated with the sea cucumber Neopentadactyla mixta or the brittle star Ophiopsila annulosa.[5]
