Description

Corophium volutator is a slender animal, up to 11 millimetres (0.43 in) long, "whitish with brown markings".[5] The head bear two pairs of antennae, the first of which are small and point forwards, while the distinctive second pair are much longer and thicker.[5]

Life cycle

There are 1–2 generations per year,[6] and the females brood the eggs inside their brood pouch or marsupium.[7] They can occur in huge quantities: up to 60,000 per square metre have been observed.[7]
