Genera: [1]
Traditionally, the Myodocopa and Podocopa have been classified as subclasses within the class Ostracoda, although there is some question about how closely related the two groups actually are. The Myodocopa are defined by possession of a poorly calcified carapace, and 8–9 articles in the exopod of the second antenna. The ventral margin of the carapace is not concave, and the valves do not overlap to a great extent.
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 Over the last thirty years there has been much research into the morphology, behaviour and distribution of myodocopids. More recently, DNA sequences have been used to investigate the phylogeny of various groups.
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.
Polycopidae is a family of marine ostracods. Its members are related to animals in the suborder Halocypridina, but are sufficiently distinct to be placed in their own sub-order, Cladocopina. There is speculation that a separate order may be warranted. The genera in the family differ from the other suborder, Halocypridina, in several features: the central adductor muscle scars are in a triangular or half-rosette pattern, they lack sixth and seventh limbs, and the maxilla has both an exopod and endopod.
Cypridinidae is a family of ostracods, containing the following genera:
Mount Milton is a mountain 3,000 metres (10,000 ft) high located 11 nautical miles (20 km) south-southeast of Mount Craddock and 1.5 nautical miles (3 km) southeast of Mount Southwick, in the southern part of the Sentinel Range in the Ellsworth Mountains of Antarctica. It overlooks Kornicker Glacier to the northeast and Sirma Glacier to the west. Mount Milton was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1957–59, and was named by the Advisory Committee on Antarctic Names for Patrick G. Milton, aviation machinist's mate, U.S. Navy, who served as plane captain on a reconnaissance flight to these mountains on January 28, 1958.
Mount Liptak is a mountain, 3,052 metres (10,013 ft) high with twin summits, located 7 nautical miles (13 km) southeast of Mount Craddock in the Sentinel Range of the Ellsworth Mountains in Antarctica. It surmounts Bolgrad Glacier to the west and Kornicker Glacier to the east.
Mount Southwick is a mountain in Owen Ridge near the south end of the Sentinel Range of the Ellsworth Mountains in Antarctica, located 9 nautical miles (17 km) south-southeast of Mount Craddock. The peak surmounts Bolgrad Glacier to the northwest, Kornicker Glacier to the east and Sirma Glacier to the southwest.
Thomas Glacier is a roughly Z-shaped glacier which drains the southeast slopes of Vinson Massif and flows for 17 nautical miles (31 km) through the south part of the Sentinel Range, Ellsworth Mountains, leaving the range between Doyran and Petvar Heights south of Johnson Spur.
Kornicker Glacier is a glacier draining northeastwards from the cirque bounded by Mount Liptak, Mount Southwick, Mount Milton and Mount Mullen in the southern Sentinel Range of the Ellsworth Mountains in Antarctica. The glacier flows along the northwestern side of Petvar Heights and merges with the terminus of the southeast-flowing Thomas Glacier as both glaciers emerge from the range.
Kasilag Pass is an ice-covered saddle of elevation 2,150 metres (7,050 ft) in the Ellsworth Mountains of Antarctica. It is situated west of Mount Mullen, separates Petvar Heights to the east from Owen Ridge, the southernmost portion of the main crest of Sentinel Range to the west, and is part of the glacial divide between Kornicker Glacier to the north and Wessbecher Glacier to the south.
Petvar Heights are the heights rising to 2400 m at Mount Mullen in southeast Sentinel Range, Ellsworth Mountains in Antarctica. The heights occupy an oval shaped area with a diameter of 21 km, separated from the rest of Sentinel Range by Wessbecher Glacier to the southwest, Kasilag Pass to the west, and Kornicker Glacier to the northwest and north. Their interior is drained by Hudman, Carey, Razboyna, Gabare and Divdyadovo Glaciers.
Bagra Peak is the peak rising to 2100 m in the north part of Petvar Heights, southeast Sentinel Range in Ellsworth Mountains, Antarctica, and overlooking Kornicker Glacier to the northwest, Razboyna Glacier to the northeast, and Drama Glacier to the east.
Mount Mullen is a double-peaked mountain 4.0 kilometres (2.5 mi) east-southeast of Mount Milton in the south Sentinel Range of the Ellsworth Mountains, Antarctica. Located at the west extremity of Petvar Heights, the mountain rises to an elevation of 2,400 metres (7,900 ft) and together with Kasilag Pass forms the divide between Kornicker Glacier and Wessbecher Glacier.
Azygocypridina is a genus of ostracods in the family Cypridinidae, which appears to be "the least derived living ostracod", having remained largely unchanged for 350 million years. It contains the following species:
Razboyna Glacier is the 3 nautical miles long and 1 nautical mile wide glacier in Petvar Heights on the southeast side of Sentinel Range in Ellsworth Mountains, Antarctica situated north of Drama Glacier, east of Kornicker Glacier, and south of the lower course of Thomas Glacier. It is draining the north slopes of Bagra Peak, and flowing northeastwards to leave the range north of Long Peak.
Thaumatocyprididae is a family of ostracods in the order Halocyprida which contains seven genera and one subfamily. It appeared in the Lopingian Epoch, 259.9 million years ago.
Vargula tsujii is a bioluminescent cypridinid ostracod found in southern California. It feeds on dead and decaying fish and invertebrates. Vargula tsujii is an important prey item of the plainfin midshipman fish, as it is the source of luciferin for the bioluminescence seen in the fish.
Cytherella is a genus of seed shrimp in the Cytherellidae family.
Deeveyidae is a family of ostracods belonging to the order Halocyprida.
