hooded shrimp - Britannica.com
A group of small, predominantly marine crustaceans immediately recognizable by their unusual body shape. The head and thorax are wide and rounded, in sharp contrast to the slender, cylindrical, flexible abdomen from which extends a long, forked tail. About 1,000 species are known. The body of most hooded shrimp measures from 2 to 10 millimetres (0.08 to 0.4 inch) long, though that of the giant arctic species Diastylis goodsiri occasionally reaches a length of more than 30 mm. Cumaceans are sometimes found intertidally, but they are most abundant in shallow offshore waters. [eng] |

Cumaceans of Southern Australia
Cumaceans are a most unusual group of Crustaceans. In general they have an inflated carapace which may be strongly ornamented with spikes or horns, a narrow abdomen and thin forked tail. Cumaceans are almost exclusively marine but estuarine species do occur. Usually, they burrow into the surface of sandy and muddy sediments but they can also be found on 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 also grazing on the surface of sand grains. There are several different families of cumaceans but only two are common. [eng] |
