Krausella is an extinct genus of ostracods. [1] It is the sole genus in family Krausellidae. [2]
It includes two species: [1]
The Clionidae are a family of sea angels, which are a group of pelagic marine gastropods.
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.
Tegula is a genus of small to medium-sized sea snails, marine gastropod molluscs in the family Tegulidae.
Atlanta is a genus of pelagic marine gastropod molluscs in the family Atlantidae. They are sometimes called heteropods.
Trimusculus is a genus of medium-sized air-breathing sea snails or false limpets, marine pulmonate gastropod molluscs in the family Trimusculidae.
The Podocopa are a subclass of ostracods. Members of the subclass Podocopa can be differentiated from the other subclass of ostracods (Myodocopa) by the morphology of the second antenna: the Podocopa have a relatively long endopod, whereas the Myodocopa have a relatively long exopod. The seventh limb of the Podocopa has a variety of forms or is absent, but is never an annulated worm-like limb.
Boonea is a small genus of small sea snails, pyramidellid gastropod mollusks.
Liotiidae is a family of small sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Crepidula, commonly known as the slipper snails, slipper limpets, or slipper shells, is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae. This family includes the slipper snails (Crepidula), hat snails (Calyptraea), spiny slipper snails (Bostrycapulus), and cup-and-saucer snails (Crucibulum) as well as Crepipatella, Siphopatella, Grandicrepidula, and Maoricrypta.
Myodocopina is a suborder of ostracods.
Kleinella is a small genus of sea snails, pyramidellid gastropod mollusk or micromollusks. This genus is currently placed in the subfamily Turbonillinae.
Cerithidea is a genus of medium-sized sea snails or mud snails, marine gastropod mollusks in the family Potamididae, the horn snails.
Zoila is a genus of sea snails, marine gastropod molluscs in the family Cypraeidae, the cowries.
Ebala is a genus of sea snails, marine gastropod mollusks in the subfamily Ebalinae, family Murchisonellidae.
Toledonia is a genus of sea snails, marine gastropod molluscs in the family Cylichnidae.
Crenella is a genus of bean mussels in the family Mytilidae.
Lomanotus is a genus of sea slugs, marine gastropod mollusks in the family Lomanotidae.
Cytherella fragum is a species of seed shrimp in the family Cytherellidae.
