Gynodiastylidae
Gynodiastylidae is one of the eight most commonly recognised families of crustaceans of the order Cumacea. They are especially prevalent in the southern hemisphere, with some types described from Japan, Thailand and the Persian Gulf. Most are found at less than depth. Anatomy Gynodiastylidae have a small free telson, usually lacking terminal setae, though in some cases there may be two. The interior branch (endopod) of the uropods is present on segments one through three. The number of free thoracic somites is never reduced. The first pereopods have a group of long rigid fibres (setae) on the propodus. Males have no pleopods. The flagellum of the second Antenna (biology), antenna does not reach further than the hindmost edge of the carapace. Females have a very small second antenna (much smaller than the first). They also have no exopods (outer branches) on their third maxillipeds. Because they lack exceptions to the two most important diagnostic characteristics (the lack of ple ...

Hooded Shrimp
Cumacea is an order of small marine crustaceans of the superorder Peracarida, occasionally called hooded shrimp or comma shrimp. Their unique appearance and uniform body plan makes them easy to distinguish from other crustaceans. They live in soft-bottoms such as mud and sand, mostly in the marine environment. There are more than 1,500 species of cumaceans formally described. The species diversity of Cumacea increases with depth. Anatomy Cumaceans have a strongly enlarged cephalothorax with a carapace, a slim abdomen, and a forked tail. The length of most species varies from . The carapace of a typical cumacean is composed of several fused dorsal head parts and the first three somites of the thorax. This carapace encloses the appendages that serve for respiration and feeding. In most species, there are two eyes at the front side of the head shield, often merged into a single dorsal eye lobe. The five posterior somites of the thorax form the pereon. The pleon (abdomen) consist ...
