The sternum is the ventral portion of a segment of an arthropod thorax or abdomen.
A tergum is the dorsal ('upper') portion of an arthropod segment other than the head. The anterior edge is called the base and posterior edge is called the apex or margin. A given tergum may be divided into hardened plates or sclerites commonly referred to as tergites. For a detailed explanation of the terminology, see Kinorhynchs have tergal and sternal plates too, though seemingly not homologous with those of arthropods.
Phuwiangosaurus is a genus of titanosauriform dinosaur from the Early Cretaceous (Valanginian-Hauterivian) Sao Khua Formation of Thailand. The type species, P. sirindhornae, was described by Martin, Buffetaut, and Suteethorn in 1994; it was named to honour Princess Maha Chakri Sirindhorn of Thailand, who was interested in the geology and palaeontology of Thailand.
Gastón Guzmán Huerta, a Mexican mycologist and anthropologist, was an authority on the genus Psilocybe.
Crocidura phanluongi is a species of shrew in the genus Crocidura from southern Vietnam and nearby Cambodia. It is a somewhat small, gray shrew with an ecologically diverse distribution.
Cyclorhagida is an order of kinorhynchs, which are small marine invertebrates.
Antygomonas is a genus of cyclorhagids. It is the only genus in the family Antygomonidae Adrianov & Malakhov, 1994. Species of Antygomonas are commonly referred to as "mud dragons."
Rugiloricus is a genus of marine organisms of the phylum Loricifera and the family Pliciloricidae, described by Higgins & Kristensen in 1986.
Virgibacillus is a genus of Gram-positive, rod-shaped (bacillus) bacteria and a member of the phylum Firmicutes. Virgibacillus species can be obligate aerobes, or facultative anaerobes and catalase enzyme positive. Under stressful environmental conditions, the bacteria can produce oval or ellipsoidal endospores in terminal, or sometimes subterminal, swollen sporangia. The genus was recently reclassified from the genus Bacillus in 1998 following an analysis of the species V. pantothenticus. Subsequently, a number of new species have been discovered or reclassified as Virgibacillus species.
Urnaloricus is a genus of loriciferans, distinct enough to belong in its own family, Urnaloricidae. Adult specimens are unknown, and are not thought to form part of the animal's lifecycle.
Skeletonema dohrnii is a diatom. Together with S. marinoi, this species has flattened extremities of the processes of the fultoportulae, which interlock with those of succeeding valves without forming knuckles.
Echinoderes obtuspinosus is a species of mud dragons first found in coastal and subtidal locations around the Korean Peninsula and in the East China Sea.
Echinoderes cernunnos is a species of mud dragons first found in coastal and subtidal locations around the Korean Peninsula and in the East China Sea.
Echinoderes aspinosus is a species of mud dragons first found in coastal and subtidal locations around the Korean Peninsula and in the East China Sea.
Echinoderidae is a family of kinorhynchs in the order Cyclorhagida.
Cephalorhyncha is a genus of kinorhynchs in the family Echinoderidae.
Meristoderes is a genus of kinorhynchs in the family Echinoderidae.
Polacanthoderes is a genus of kinorhynchs in the family Echinoderidae. It consists of one species, Polacanthoderes martinezi Sørensen, 2008.
Echinoderes is a genus of mud dragons first described in 1863. It is the largest genus within class Kinorhyncha. It is a highly diverse genus, with member species that inhabit "most marine benthic substrates, on latitudes ranging from the Arctic to the tropics, and from the intertidal zone down to the deep sea." Species on the east coasts of North and South America have been extensively studied by Robert P. Higgins. Species in east Asia have been extensively studied by A. V. Adrianov.
