Myodocopida

The Myodocopida is one of the two orders within the Myodocopa, in turn a subclass of the Ostracoda. The Myodocopida are distinguished by a worm-like seventh limb, and, usually, a rostrum above an incisure (notch) from which the antennae can protrude. Unlike other ostracods, many species of the Myodocopida have lateral compound eyes Research on the cypridinid species Macrocypridina castanea have shown that the ‘window’ above its eyes—a transparent area on the shell—contains a nanostructure that transmits an unusually high 99% of blue light (350–630 nm)—the predominant light in its environment—a

Cylindroleberididae is a family of ostracods that shows remarkable morphological diversity. The defining feature is the possession of gills: 7–8 leaf-like pairs at the posterior of the body. Other features common to all species in the family include a "baleen-comb" on both the maxilla and the fifth limb, a sword-shaped coxal endite on the mandible, and the triaenid bristles on the basal endites of the mandible.

Cypridinidae is a family of ostracods. About half of all known species are bioluminescent. Some use the light only for defence, others also for courtship displays. The lineages with sexually dimorphic bioluminescent displays have more species other lineages, which indicates that bioluminescent courtship could increase the diversification rates.

Gigantocypris, sometimes known as giant ostracod or giant seed shrimp, is a genus of ostracod crustaceans in family Cypridinidae, and among the most well-known members of the class Ostracoda (together with Vargula hilgendorfii). Its members are extremely large for ostracods, measuring up to across, have a globular shape, are typically semi-transparent orange or reddish, and have a large pair of mirror-like eyes that are used to locate their small animal prey. They are found worldwide in dark, deep and cold oceans.

Vargula is a genus in the Cypridinidae. The genus contains bioluminescent species. Vargula hilgendorfii (formerly Cypridina hilgendorfii), native to Japan, is likely the best-studied Vargula. Some species currently within Vargula (e.g. Vargula tsujii) may be split into their own genus.
