Cirolana cranchii is a species of isopod crustacean.
Cirolana cranchii was described by the English zoologist William Elford Leach in 1818; he named the genus anagramatically after an unknown woman called Caroline/Carolina, and the species after his friend and collector John Cranch. [3] [4]
C. cranchii is the type species of the genus Cirolana, which in turn is the type genus for the family Cirolanidae. [2] The type locality is Cornwall, Great Britain. [1] [2]
The species is found around the British Isles and the northwestern coasts of Portugal, Spain and France, with the greatest abundance around the western coasts of Ireland, Cornwall and Brittany. [5] The species has also been recorded from the North Sea, the Mediterranean, and the coasts of Australia. [6] Bruce and Ellis consider only the eastern North Atlantic and Mediterranean records reliable. [2]
The adult male is between 9.0 and 19.1 mm long and about 3 times as long as it is wide. The head (cephalon) lacks a forward-pointing spine (rostral process). The body consists of 11 visible segments each covered in a smooth dorsal scale behind the head, with a triangular tail (pleotelson). [2] There are six joints to the abdomen. The legs are used for walking and have small claws. [4] Tail paddles (uropods) extend beyond the point of the tail. The female has a wider pleotelson and non-angled uropods, and lacks the dense bristles (setae) on these parts. Females are between 9.6 and 19.2 mm long. Young males resemble females. [2]
William Elford Leach FRS was an English zoologist and marine biologist.
Isopoda is an order of crustaceans that includes woodlice and their relatives. Isopods live in the sea, in fresh water, or on land. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration. Females brood their young in a pouch under their thorax.
Iphinoe trispinosa is a species of cumacean belonging to the family Bodotriidae and the genus Iphinoe.
The Cymothoidae are a family of isopods in the suborder Cymothoida found in both marine and freshwater environments. Cymoithoids are ectoparasites, usually of fish, and they include the bizarre "tongue-biter", which attaches to a fish's tongue, causing it to atrophy, and replaces the tongue with its own body. Ceratothoa oestroides is one of the most devastating ectoparasites in Mediterranean aquaculture. Around 40 genera and more than 380 species of cymothoid are recognised. Species of the Cymothoidae are generally found in warmer waters and rarely in the cool and cold climates.
A giant isopod is any of the almost 20 species of large isopods, crustaceans distantly related to shrimp and crabs, which are decapods, in the genus Bathynomus. They are abundant in the cold, deep waters of the Atlantic, Pacific, and Indian Oceans. Bathynomus giganteus, the species upon which the generitype is based, is often considered the largest isopod in the world, though other comparably poorly known species of Bathynomus may reach a similar size. The giant isopods are noted for their resemblance to the much smaller common woodlouse, to which they are related.
Archaeoniscus is a genus of prehistoric isopods that first appeared during the Bajocian stage of the Middle Jurassic. It is a widespread genus with a paleogeographic distribution encompassing the continental margin environments of the central Atlantic Ocean and the western Tethys Ocean. Fossils of Archaeoniscus suggest that this genus lived in diverse aquatic habitats, including the marine, paralic, and freshwater environments. While earlier descriptions suggested that it may have had an ectoparasitic association with fishes, some researchers argue that at least two species, A. aranguthyorum and A. coreaensis, lived a benthic free-living lifestyle based on morphological characteristics that are either unsuitable for or unrelated to parasitic behavior.
Scyllarides latus, the Mediterranean slipper lobster, is a species of slipper lobster found in the Mediterranean Sea and in the eastern Atlantic Ocean. It is edible and highly regarded as food, but is now rare over much of its range due to overfishing. Adults may grow to 1 foot (30 cm) long, are camouflaged, and have no claws. They are nocturnal, emerging from caves and other shelters during the night to feed on molluscs. As well as being eaten by humans, S. latus is also preyed upon by a variety of bony fish. Its closest relative is S. herklotsii, which occurs off the Atlantic coast of West Africa; other species of Scyllarides occur in the western Atlantic Ocean and the Indo-Pacific. The larvae and young animals are largely unknown.
Inachus phalangium, Leach's spider crab, is a species of crabs from the north-eastern Atlantic Ocean and Mediterranean Sea. It is up to 20.5 mm (0.81 in) wide, and is very similar to other species in the genus Inachus.
Ibacus ciliatus is a species of slipper lobster from the north-west Pacific Ocean.
Albunea carabus is a rare species of "sand crab" or "mole crab" in the genus Albunea. It lives in shallow, turbulent waters in sandy areas of the tropical eastern Atlantic Ocean and the Mediterranean Sea.
Aega antarctica is a species of isopod crustacean. It is a temporary ectoparasite of fish, feeding on the fish's blood and then dropping to the seabed to digest its meal over a period of several months. It is found in the seas around Antarctica.
Uromunna sheltoni is a species of isopod first described by Brian Kensley in 1977. U. sheltoni is included in the genus Uromunna and family Munnidae. No subspecies are listed. The species was first collected by Peter Shelton of the University of Cape Town, for whom it is named.
Cirolana is a genus of isopod crustaceans.
Exosphaeroma amplicauda is a species of marine isopod of the family Sphaeromatidae.
Ceratothoais a genus of isopod ectoparasites of teleost fish, first described by James Dwight Dana in 1852. Infection by Ceratothoa can cause anaemia, lesions, growth retardation, emaciation, and mortality in their fish hosts.
Scutuloidea maculata is a species of marine isopods in the family Sphaeromatidae, first described by Charles Chilton in 1883. No subspecies are listed in the Catalogue of Life.
Speocirolana xilitla is a species of crustacean in the family Cirolanidae. It is known from a cave near Xilitla, San Luis Potosi. The specific name refers to this town. It is the southernmost species in the genus Speocirolana.
Aatolana schioedtei is a species of crustaceans in the family Cirolanidae, first described by Edward J. Miers in 1884 as Cirolana schioedtei. In 1993, Bruce reasssigned the species to the genus, Aatolana.
Natatolana is a genus of crustaceans in the family Cirolanidae, first described by Niel L. Bruce in 1981. The type species is Cirolana hirtipes Milne Edwards, 1840.
Natatolana neglecta is a species of crustacean in the family Cirolanidae, and was first described by Hans Jacob Hansen in 1890 as Cirolana neglecta, It was redescribed as Natatolana neglecta by Stephen Keable and Niel L. Bruce in 1997.
