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.
Soft bottom, from sand, to depths of 12 m.
Southern temperate oceans, including western and southern Australia.
