Vermes ("worms") is an obsolete taxon used by Carl Linnaeus and Jean-Baptiste Lamarck for non-arthropod invertebrate animals.
The family Cranchiidae comprises the approximately 60 species of glass squid, also known as cockatoo squid, cranchiid, cranch squid, or bathyscaphoid squid. Cranchiid squid occur in surface and midwater depths of open oceans around the world. They range in mantle length from 10 cm (3.9 in) to over 3 m (9.8 ft), in the case of the colossal squid. The common name, glass squid, derives from the transparent nature of most species. Cranchiid squid spend much of their lives in partially sunlit shallow waters, where their transparency provides camouflage. They are characterised by a swollen body and short arms, which bear two rows of suckers or hooks. The third arm pair is often enlarged. Many species are bioluminescent organisms and possess light organs on the undersides of their eyes, used to cancel their shadows. Eye morphology varies widely, ranging from large and circular to telescopic and stalked. A large, fluid-filled chamber containing ammonia solution is used to aid buoyancy. This buoyancy system is unique to the family and is the source of their common name "bathyscaphoid squid", after their resemblance to a bathyscaphe. Often the only organ that is visible through the transparent tissues is a cigar-shaped digestive gland, which is the cephalopod equivalent of a mammalian liver. This is usually held in a vertical position to reduce its silhouette and a light organ is sometimes present on the lower tip to further minimise its appearance in the water.
King crabs are decapod crustaceans of the family Lithodidae that are chiefly found in deep waters and are adapted to cold environments. They are composed of two subfamilies: Lithodinae, which tend to inhabit deep waters, are globally distributed, and comprise the majority of the family's species diversity; and Hapalogastrinae, which are endemic to the North Pacific and inhabit exclusively shallow waters. King crabs superficially resemble true crabs but are generally understood to be closest to the pagurid hermit crabs. This placement of king crabs among the hermit crabs is supported by several anatomical peculiarities which are present only in king crabs and hermit crabs, making them a prominent example of carcinisation among decapods. Several species of king crabs, especially in Alaskan and southern South American waters, are targeted by commercial fisheries and have been subject to overfishing.
John Cranch (1785–1816) was an English naturalist and explorer.
Carcinisation is a form of convergent evolution in which non-crab crustaceans evolve a crab-like body plan. The term was introduced into evolutionary biology by L. A. Borradaile, who described it as "the many attempts of Nature to evolve a crab".
Thalassinidea is a former infraorder of decapod crustaceans that live in burrows in muddy bottoms of the world's oceans. In Australian English, the littoral thalassinidean Trypaea australiensis is referred to as the yabby, frequently used as bait for estuarine fishing; elsewhere, however, they are poorly known, and as such have few vernacular names, "mud lobster" and "ghost shrimp" counting among them. The burrows made by thalassinideans are frequently preserved, and the fossil record of thalassinideans reaches back to the late Jurassic.
Giuseppe Antonio Risso, called Antoine Risso, was a naturalist from Nice.
Alexander von Nordmann was a 19th-century Finnish biologist, who contributed to zoology, parasitology, botany and paleontology.
The hairy stone crab is a crab-like anomuran crustacean that lives in the littoral zone of southern Australia from Bunbury, Western Australia, to the Bass Strait. It is the only species in the family Lomisidae. It is 1.5–2.5 cm (0.6–1.0 in) wide, slow-moving, and covered in brown hair which camouflages it against the rocks upon which it lives.
Hippoidea is a superfamily of decapod crustaceans known as mole crabs or sand crabs.
Isabella Gordon OBE FZS FLS was a Scottish marine biologist who specialised in carcinology and was an expert in crabs and sea spiders. She worked at the Natural History Museum and received an OBE in 1961.
Paracerceis sculpta is a species of marine isopod between 1.3 millimetres (0.05 in) and 10.3 mm (0.41 in) in length. The species lives mainly in the intertidal zone, and is native to the Northeast Pacific from Southern California to Mexico, but has since been introduced to many other countries. Adults are herbivorous and consume algae but juveniles are carnivorous and consume moulting females. They reproduce in sponges but do not feed near them.
Galatheacaris abyssalis is a rare species of shrimp, now thought to be a larval stage of another genus, Eugonatonotus.
Danièle Guinot is a French biologist, an emeritus professor at the Muséum national d'histoire naturelle in France, known for her research on crabs.
Trachysalambria curvirostris is a species of prawn that lives in shallow waters of the Indo-West Pacific. It is one of the most important species targeted by prawn fishery, with annual harvests of more than 300,000 t, mostly landed in China.
Jacques Forest was a French carcinologist.
Cirolana cranchii is a species of isopod crustacean.
Esther Fussell Byrnes (1867–1946) was an American biologist and science teacher. She was one of the first women copepodologists—scientists who study copepods. She was a fellow of the New York Academy of Sciences, as well as the American Society of Naturalists.
Pennella exocoeti is a large ectoparasitic copepod, a specialist parasite of flying fish. The adult female copepod clings to the fish's gills or skin and feeds on its body fluids.
Leptuca thayeri, known generally as the Atlantic mangrove fiddler crab or mangrove fiddler, is a species of true crab in the family Ocypodidae. It is distributed all across the Western Atlantic.
