Brief Summary

provided by Ecomare

If you are on the tidal flats on a quiet day, you can hear the corophium wallowing in the mud. They make a remarkable dry crackling sound. Corophium are very common inhabitants of the muddy flats. In the summer, their population can reach densities greater than 10,000 per square meter. They dig tunnels, from which they gather food with their long tentacles, consuming as much as 4000 diatoms per day. This amount of diatoms must be processed and therefore corophium eject wastes up to 1000 times a day.

Corophium volutator

provided by wikipedia EN

Corophium volutator is a species of amphipod crustacean in the family Corophiidae.^[2] It is found in mudflats of the northern Atlantic Ocean.^[3] It is native to the north-east Atlantic Ocean, and has been introduced to the north-west Atlantic.^[4]

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]
