Nephropsis atlantica, sometimes called the scarlet lobsterette [1] or scarlet clawed lobster, [2] is a species of lobster from the Atlantic Ocean.
Nephropsis atlantica is relatively small for a lobster, growing to a maximum total length of 103 millimetres (4.1 in). [3] [4] The eyes are unpigmented, in contrast to shallow-water species, and the carapace, abdomen and chelae are covered in setae (bristles). [4]
Nephropsis atlantica is found on muddy substrates in deep waters of the eastern Atlantic Ocean, from the Faroe Islands to Namibia. [3] [Note 1] It has been recorded at depths of 470–1,804 metres (1,500–5,900 ft), but is most frequent at 900–1,000 m (3,000–3,300 ft). [3] It is one of only three clawed lobsters in the north-east Atlantic Ocean (the others being Homarus gammarus and Nephrops norvegicus ), and the only one which is not the subject of commercial fishery. [2]
Nephropsis atlantica was first described by the Reverend Canon Alfred Merle Norman in a report sent to Charles Wyville Thomson in 1880, and published in the Proceedings of the Royal Society of Edinburgh in 1882. The report was one of several published simultaneously on the various organisms dredged up by the ship Knight Errant in the Faroe–Shetland Channel. Norman's report opens "I send a list; it is a very interesting one", and goes on to detail species known from previous expeditions to the North Atlantic and three new species – Ampelisca compacta (Amphipoda: Ampeliscidae), Halirages elegans (Amphipoda: Calliopiidae) and Nephropsis atlantica. [5] The type specimens were collected on August 10, 1880 at 59°33′N7°14′W / 59.550°N 7.233°W at a depth of 555 fathoms (3,330 ft; 1,015 m); they are presumed to have been lost since. [3]
The American lobster is a species of lobster found on the Atlantic coast of North America, chiefly from Labrador to New Jersey. It is also known as Atlantic lobster, Canadian lobster, true lobster, northern lobster, Canadian Reds, or Maine lobster. It can reach a body length of 64 cm (25 in), and a mass of over 20 kilograms (44 lb), making it not only the heaviest crustacean in the world, but also the heaviest of all living arthropod species. Its closest relative is the European lobster Homarus gammarus, which can be distinguished by its coloration and the lack of spines on the underside of the rostrum. American lobsters are usually bluish green to brown with red spines, but several color variations have been observed.
Homarus is a genus of lobsters, which include the common and commercially significant species Homarus americanus and Homarus gammarus. The Cape lobster, which was formerly in this genus as H. capensis, was moved in 1995 to the new genus Homarinus.
Homarus gammarus, known as the European lobster or common lobster, is a species of clawed lobster from the eastern Atlantic Ocean, Mediterranean Sea and parts of the Black Sea. It is closely related to the American lobster, H. americanus. It may grow to a length of 60 cm (24 in) and a mass of 6 kilograms (13 lb), and bears a conspicuous pair of claws. In life, the lobsters are blue, only becoming "lobster red" on cooking. Mating occurs in the summer, producing eggs which are carried by the females for up to a year before hatching into planktonic larvae. Homarus gammarus is a highly esteemed food, and is widely caught using lobster pots, mostly around the British Isles.
The California spiny lobster is a species of spiny lobster found in the eastern Pacific Ocean from Monterey Bay, California, to the Gulf of Tehuantepec, Mexico. It typically grows to a length of 30 cm (12 in) and is a reddish-brown color with stripes along the legs, and has a pair of enlarged antennae but no claws. The interrupted grooves across the tail are characteristic for the species.
Nephrops norvegicus, known variously as the Norway lobster, Dublin Bay prawn, shlobster (shrimp-lobster), langoustine or shrimp, is a slim, coral colored lobster that grows up to 25 cm (10 in) long, and is "the most important commercial crustacean in Europe". It is now the only extant species in the genus Nephrops, after several other species were moved to the closely related genus Metanephrops. It lives in the north-eastern Atlantic Ocean, and parts of the Mediterranean Sea, but is absent from the Baltic Sea and Black Sea. Adults emerge from their burrows at night to feed on worms and fish.
The Cape lobster, Homarinus capensis, is a species of small lobster that lives off the coast of South Africa, from Dassen Island to Haga Haga. Only a few dozen specimens are known, mostly regurgitated by reef-dwelling fish. It lives in rocky reefs, and is thought to lay large eggs that have a short larval phase, or that hatch directly as a juvenile. The species grows to a total length of 10 cm (3.9 in), and resembles a small European or American lobster; it was previously included in the same genus, Homarus, although it is not very closely related to those species, and is now considered to form a separate, monotypic genus – Homarinus. Its closest relatives are the genera Thymops and Thymopides.
Metanephrops challengeri is a species of slim, pink lobster that lives around the coast of New Zealand. It is typically 13–18 cm (5–7 in) long and weighs around 100 g (3.5 oz). The carapace and abdomen are smooth, and adults are white with pink and brown markings and a conspicuous pair of long, slim claws. M. challengeri lives in burrows at depths of 140–640 m (460–2,100 ft) in a variety of sediments. Although individuals can live for up to 15 years, the species shows low fecundity, where small numbers of larvae hatch at an advanced stage.
Reef lobsters, Enoplometopus, are a genus of small lobsters that live on reefs in the Indo-Pacific, Caribbean and warmer parts of the Atlantic Ocean.
Magnapinna atlantica, previously known as "Magnapinna sp. A", is a species of bigfin squid known from only two specimens collected in the northern Atlantic Ocean. It is characterised by several unique morphological features: the tentacle bases are narrower than adjacent arm bases, the proximal tentacle lacks suckers but possesses glandular structures, and the animal's pigment is contained mostly in functional chromatophores.
Panulirus versicolor is a species of spiny lobster that lives in tropical reefs in the Indo-Pacific. Other names include painted lobster, common rock lobster, bamboo lobster, blue lobster, and blue spiny lobster. P. versicolor is one of the three most common varieties of spiny lobster in Sri Lanka, alongside Panulirus homarus and Panulirus ornatus.
Jasus is a genus of spiny lobsters which live in the oceans of the Southern Hemisphere. They have two distinct "horns" projecting from the front of the carapace, but lack the stridulating organs present in almost all other genera of spiny lobsters. Like all spiny lobsters, they lack claws, and have long stout antennae which are quite flexible.
Polycheles typhlops is a species of blind, deep water decapod crustacean with a cosmopolitan distribution. It is "one of the dominant and most characteristic crustaceans in deep-sea communities of the Mediterranean Sea".
Nephropsis rosea, sometimes called the rosy lobsterette or two-toned lobsterette, is a species of lobster.
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.
Eunephrops manningi, the banded lobster, is a species of lobster found in the West Indies. It was named in 1974 by carcinologist Lipke Holthuis after his friend and fellow carcinologist Raymond B. Manning.
Palinurus mauritanicus is a species of spiny lobster. It is found in deep waters in the eastern Atlantic Ocean and the western Mediterranean Sea.
Eunephrops cadenasi, sometimes called the sculptured lobster, is a species of lobster found in the Caribbean.
Nephropsis is a genus of lobsters containing 18 extant species:
Panulirus guttatus, the spotted spiny lobster or Guinea chick lobster, is a species of spiny lobster that lives on shallow rocky reefs in the tropical West Atlantic and Caribbean Sea.
Jasus paulensis, also commonly known as the St Paul rock lobster, is a species of spiny lobster found in the waters around Saint Paul Island in the southern Indian Ocean and around Tristan da Cunha in the southern Atlantic Ocean. At one time the rock lobsters on Tristan da Cunha were believed to be a separate species known as the Tristan rock lobster, but the use of mitochondrial DNA sequencing has shown them to be identical. Some authorities, for example the International Union for Conservation of Nature, retain them as separate species. The Tristan rock lobster features on the coat of arms and the flag of Tristan da Cunha.
