Pleopods each with two rami, with plumose setae. First segment of endopod of uropod longer than 2nd and 3rd segments together. Females with exopod on 3rd maxilliped, without trace of exopods on 3rd and 4th pereopods. Telson present.

Biology

Cumaceans burrow into the surface of sandy and muddy sediments but can also be found in the sediment trapped among macroalgae. At night especially cumaceans can be active swimmers in the open water and this is probably where mating occurs. Food is obtained by filtering water just above the sediment and grazing on the surface of sand grains. Cumaceans can be dug out of sandy sediment but the most effective way of catching them is by attracting them to lights at night.
