Hemisquilla ensigera is a species of mantis shrimp. Two formerly recognized subspecies are now considered to be separate species ( H. californiensis , H. australiensis ). [1]
The species is a near complete "oxyconformer" in that its aerobic metabolism is significantly depressed and impacted at low oxygen levels. [2]
Mantis shrimp are carnivorous marine crustaceans of the order Stomatopoda. Stomatopods branched off from other members of the class Malacostraca around 340 million years ago. Mantis shrimp typically grow to around 10 cm (3.9 in) in length, while a few can reach up to 38 cm (15 in). A mantis shrimp's carapace covers only the rear part of the head and the first four segments of the thorax. Varieties range in colour from shades of brown to vivid colours, with more than 520 species of mantis shrimp known. They are among the most important predators in many shallow, tropical and subtropical marine habitats. However, despite being common, they are poorly understood, as many species spend most of their lives sheltering in burrows and holes.
Odontodactylus is a genus of mantis shrimp, the only genus in the family Odontodactylidae. Mantis shrimp of the genus Odontodactylus can not only detect circular polarisation of light, but can also detect polarised light reflecting off their telson and uropods.
Lysiosquilla is a genus of mantis shrimp of the family Lysiosquillidae, containing these species:
Hippolyte is a genus of shrimp in the family Hippolytidae, containing the following species:
Squilla mantis is a species of mantis shrimp found in shallow coastal areas of the Mediterranean Sea and the Eastern Atlantic Ocean: it is also known as "pacchero" or "canocchia". Its abundance has led to it being the only commercially fished mantis shrimp in the Mediterranean.
Squilla is a genus of mantis shrimp. It includes the following species:
Oratosquilla oratoria, the Japanese mantis shrimp, is a species of mantis shrimp found in the western Pacific. It is widely harvested in Japan and eaten as sushi. Like other members of its order it has a powerful spear, which it uses to hunt invertebrates and small fish. It grows to a length of 185 millimetres (7.3 in), and lives at depths of 10–100 metres (33–328 ft).
Farfantepenaeus is a genus of prawns in the family Penaeidae. Its eight species were formerly included in the genus Penaeus. It was first published as a genus name in 1972 by Rudolf N. Burukovsky, but without the necessary designation of a type species. That situation was corrected by the same author in 1997. The name Farfantepenaeus commemorates the Cuban carcinologist Isabel Pérez Farfante.
Tetrasquillidae is a family of mantis shrimp containing ten genera:
Neotrypaea is a genus of ghost shrimp in the family Callianassidae, containing the following sixteen species:
Bathysquillidae is a family of mantis shrimp. It contains two genera and three species. The family was described by Raymond Manning in 1967.
The Pseudosquillidae are a family of mantis shrimp containing four genera and 11 species.
Squilla empusa is a species of mantis shrimp found in coastal areas of the western Atlantic Ocean. It excavates and occupies a burrow in soft sediment from which it emerges, mainly at night, to feed on fish and invertebrate prey.
The clade Multicrustacea constitutes the largest superclass of crustaceans, containing approximately four-fifths of all described non-hexapod crustacean species, including crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, barnacles, copepods, amphipods, mantis shrimp and others. The largest branch of multicrustacea is the class Malacostraca.
Hippolyte californiensis, the California green shrimp, is a species of shrimp in the family Hippolytidae. It is native to the eastern Pacific Ocean. It was first described in 1895 by the zoologist S.J. Holmes from Bodega Bay, California. Of the 32 or so species in the genus Hippolyte, it is most closely related to H. obliquimanus and H. williamsi.
Hemisquilla is a genus of mantis shrimp, and the only genus in the family Hemisquillidae. It contains four species distributed in Australia and the Americas. Species in the genus typically eat snails, fish, rock oysters, and smaller crustaceans like crabs. They are preyed upon by larger bony fishes and cephalopods. It is the most basal living mantis shrimp lineage, and the sister group to all other mantis shrimp.
Hemisquilla australiensis is a species of mantis shrimp native to Australia and also found in New Zealand.
Hemisquilla braziliensis is a species of mantis shrimp native to South America.
Hemisquilla californiensis is a species of mantis shrimp native to the northern Pacific Ocean. H. californiensis is known for smashing prey against rocks using its raptorial claws, as well as its brightly colored telson and eyespots under the tail. H. californiensis is one of the largest and most common mantis shrimp species in California. H. californiensis is one of three subspecies of H. ensigera.
Pariliacantha is a genus of mantis shrimp containing a single species, Pariliacantha georgeorum. The genus and species were first described by Shane T. Ahyong in 2012.
