Benthesicymidae is a family of shrimps in the suborder Dendrobranchiata.
The Caridea, commonly known as caridean shrimp or true shrimp, are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp.
The Decapoda or decapods are an order of crustaceans within the class Malacostraca, including many familiar groups, such as crabs, lobsters, crayfish, shrimp and prawns. Most decapods are scavengers. The order is estimated to contain nearly 15,000 species in around 2,700 genera, with around 3,300 fossil species. Nearly half of these species are crabs, with the shrimp and Anomura including hermit crabs, porcelain crabs, squat lobsters making up the bulk of the remainder. The earliest fossil decapod is the Devonian Palaeopalaemon.
Lucifer is a little-known and degenerate genus of prawns, the type genus of the family Luciferidae. Lucifer has a long body, but many fewer appendages than other prawns, with only three pairs of pereiopods remaining, all without claws. It also bears no gills. The females, uniquely among prawns, carry the fertilised eggs on her pleopods until they are ready to hatch. This parallels the development of a similar system in pleocyemates, although the attachment is less strong in Lucifer. The length of the eye-stalks and the form of the petasma are used in distinguishing the eight species from each other.
Luciferidae is a family of prawns. These prawns are small, characterised by bioluminescence and the loss or reduction of some appendages. They are predators of tiny planktonic crustaceans for which their third pereiopod is adapted to capture by having thick, curved spines covering the limb. Until recently, the family was thought to be monotypic, but a 2016 cladistic analysis recognized a second genus apart from Lucifer, named Belzebub.
Petromuridae is a family of hystricognath rodents that contains the dassie rat (Petromus typicus) of southwestern Africa, the only extant member of this group.
Thryonomyidae is a family of hystricognath rodents that contains the cane rats (Thryomys) found throughout sub-Saharan Africa, and a number of fossil genera.
The Sesarmidae are a family of crabs, previously included in the Grapsidae by many authors. Several species, namely in Geosesarma, Metopaulias, and Sesarma, are true terrestrial crabs. They do not need to return to the sea even for breeding.
Bunodes is a genus of synziphosurine, a paraphyletic group of fossil chelicerate arthropods. Bunodes was regarded as part of the clade Planaterga. Fossils of the single and type species, B. lunula, have been discovered in deposits of the Silurian period in Ludlow, England. Bunodes is the type genus of the family Bunodidae, the other genera of the same family being Limuloides.
The Forcipulatida are an order of sea stars, containing three families and 49 genera.
Benthesicymus is a genus of prawns, containing the following species:
Drilini is a tribe of beetles known commonly as the false firefly beetles, in the family Elateridae.
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region. However, one species, Obama nungara has been introduced in Europe.
Lucensosergia lucens is a species of shrimp popularly known as the sakura shrimp or sakura ebi. The translucent pink shrimp derives its name from sakura, the Japanese word for the cherry blossom. The species grows to about 4–5 cm and lives primarily in Suruga Bay in Shizuoka Prefecture, Japan, where it is caught to be eaten. It is also caught in Taiwan.
Arthrotardigrada are an order of tardigrades, first described by Marcus in 1927.
Belzebub is a genus of prawns in the family Luciferidae. The species which make up the genus Belzebub were formerly placed in the genus Lucifer but were separated to form Belzebub after a cladistic analysis. They are very small planktonic and benthic prawns with an extreme lateral compression of the carapace with elongated mandibles and anteriors of the pereiopods but lacking pereiopods 4 and 5 and any gills. The pereiopods either lack chelae or they are substantially reduced. The sixth abdominal segment of males has two ventral processes and the telson has a strong ventral process.
Belzebub hanseni, the ghost shrimp or ghost prawn, is a small planktonic and benthic species of prawn from the family Luciferidae.
Showajidaia sagamiensis is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Showajidaiidae.
Showajidaiidae is a family of sea slugs, dorid nudibranchs, marine gastropod mollusks in the superfamily Chromodoridoidea.
Showajidaia is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks.
The Forcipulatacea are a superorder of sea stars.
