| Pandalus montagui | |
Pandalus montagui is a species of cold-water shrimp in the family Pandalidae. It is the type species of the genus Pandalus and is variously known as the pink shrimp, Aesop shrimp and Aesop prawn. [2]
Pandalus montagui is a translucent, pinkish shrimp, generally growing to about 5 cm (2.0 in) long. Its colour is due to a number of red chromatophores and the few short red streaks running obliquely on the carapace. The rostrum is long, up-curved and divided at the tip with 10–12 teeth on its posterior dorsal edge. A spine is found under the eye on the carapace. The first antenna divides into two parts and the second is very long, exceeding the length of the body and being banded in pale and dark brown. [3] [4] This shrimp can be distinguished from the rather similar P. tridens by having a shorter rostrum and longer dactyls (claws) on the third and fourth pereopods (walking limbs). [5]
Pandalus montagui has a boreo-arctic distribution. Its range extends from Greenland and Iceland, the Arctic Ocean, and the northern Atlantic Ocean, south to Rhode Island and the British Isles. [5] It prefers hard substrates, but can be found on rock, gravel, sand, and mud. It is most common at depths between 20 and 100 m (66 and 328 ft), but sometimes occurs near low-water mark or at depths to 700 m (2,300 ft). [2]
Pandalus montagui is an omnivore, predator, and scavenger. [1] Its diet consists mainly of small crustaceans such as copepods, hydroids, and polychaete worms. [3] Off the Labrador coast, a large daily vertical migration was found, with the shrimp being benthic in the daytime and pelagic at night. [6]
Most individuals start life as males, but change sex to females at 12–15 months old. In the North Sea, off Britain, each female lays 2000–3000 eggs in November. When fertilised, she carries them around for a few days on her periopods. They then hatch and go through six zoeal and two to five decapod planktonic larval stages before undergoing metamorphosis and settling as juveniles. The rate of development of the larvae depends on the water temperature. In the more temperate parts of the range, the shrimp mature within a year. [7]
In the North Sea, P. montagui is often found living in association with the polychaete worm Sabellaria spinulosa . The worm sometimes forms cold-water reefs, and these are an important source of food for the shrimp. Fishermen have used this fact by identifying the locations of reefs and then trawling for shrimp nearby. [8]
The Aesop shrimp is sometimes found to be parasitized by the bopyrid isopod, Hemiarthrus abdominalis . This isopod also parasitizes several other species of shrimp, but has never been found on Pandalus borealis . [9]
This species is fished commercially in the United Kingdom, but mostly taken as an alternative to the larger P. borealis. About 500 tons a year of P. montagui were caught globally in the period 2005–2007, catches also being recorded from Belgium, Denmark, the Faröe Islands, the Netherlands, Iceland, Norway, and Sweden. [2]
The Caridea, commonly known as caridean shrimp or true shrimp, from the Greek word καρίς, καρίδος, are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp.
Isopoda is an order of crustacean, which includes woodlice and their relatives. Members of this group are called Isopods and include both terrestrial and aquatic species. 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.
Nephrops norvegicus, known variously as the Norway lobster, Dublin Bay prawn, shlobster (shrimp-lobster), langoustine or scampi, 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.
Pandalus borealis is a species of caridean shrimp found in cold parts of the northern Atlantic and northern Pacific Oceans, although the latter population now often is regarded as a separate species, P. eous. The Food and Agriculture Organization refers to them as the northern prawn. Other common names include pink shrimp, deepwater prawn, deep-sea prawn, Nordic shrimp, great northern prawn, northern shrimp, coldwater prawn and Maine shrimp.
Amphionides reynaudii is a species of caridean shrimp, whose identity and position in the crustacean system remained enigmatic for a long time. It is a small planktonic crustacean found throughout the world's tropical oceans, which until 2015 was considered the sole representative of the order Amphionidacea, due to unusual morphological features. Molecular data however confirm it as a member of the caridean family Pandalidae, and the confusion of morphology is because only larval phases have so far been studied.
Gilvossius tyrrhenus is a species of thalassinidean crustacean which grows to a length of 70 mm (2.8 in). It lives in burrows in shallow sandy parts of the sea-bed in the Mediterranean Sea and northern Atlantic Ocean. It is the most common thalassinidean in the Mediterranean, and has been used as bait by fishermen for at least 200 years.
Heterocarpus is a genus of deep-sea shrimp, mainly of tropical areas all over the world.
Crustaceans may pass through a number of larval and immature stages between hatching from their eggs and reaching their adult form. Each of the stages is separated by a moult, in which the hard exoskeleton is shed to allow the animal to grow. The larvae of crustaceans often bear little resemblance to the adult, and there are still cases where it is not known what larvae will grow into what adults. This is especially true of crustaceans which live as benthic adults, more-so than where the larvae are planktonic, and thereby easily caught.
Lernaeocera branchialis, sometimes called cod worm, is a parasite of marine fish, found mainly in the North Atlantic. It is a marine copepod which starts life as a small pelagic crustacean larva. It is among the largest of copepods, ranging in size from 2 to 3 millimetres when it matures as a copepodid larva to more than 40 mm as a sessile adult.
Pinnixa chaetopterana, the tube pea crab, is a small decapod crustacean that lives harmlessly within the tube of the polychaete worm, Chaetopterus variopedatus.
Sabellaria spinulosa is a species of marine polychaete worm in the family Sabellariidae, commonly known as the Ross worm. It lives in a tube built of sand, gravel and pieces of shell.
Pandalus is a genus of shrimp in the family Pandalidae. Members of the genus are medium-sized and live on or near the seabed. Some species are the subject of commercial fisheries and are caught by trawling. One species, Pandalus montagui, lives in association with the reef-building polychaete worm, Sabellaria spinulosa.
A shrimp is a crustacean with an elongated body and a primarily swimming mode of locomotion – typically belonging to the Caridea or Dendrobranchiata of the decapod order, although some crustaceans outside of this order are also referred to as "shrimp".
Prawn is a common name for small aquatic crustaceans with an exoskeleton and ten legs, some of which are edible.
Crustaceans belong to the subphylum Crustacea, and form a large, diverse group of arthropods including decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans.
Aristaeomorpha foliacea, the giant red shrimp or giant gamba prawn, is a species of deep water benthopelagic decapod crustacean. It is found in all the world's oceans in the temperate and tropical zones. It is subject to some commercial fishing activity in the Mediterranean Sea.
Upogebia pugettensis, also known as the blue mud shrimp, is a species of mud lobster from the West Coast of North America.
Neaeromya rugifera is a species of bivalve that inhabits the West Coast of North America.
Pandalus hypsinotus is a crustacean in the Pandalidae family, ordinarily 10–12.5 centimetres (3.9–4.9 in) in length, but large females may reach 17.5 centimetres (6.9 in). It can be found in the Bering Sea, from the Aleutian Islands to Puget Sound, and in the Sea of Japan at depths of 100–200 metres (330–660 ft).
Caridina typus, also known as the Australian Amano Shrimp, is a species of amphidromous atyid shrimp. It was first described by H. Milne-Edwards in 1837. It has a broad distribution in tropical freshwater habitats in the Indo-West Pacific region, with its western range extending to eastern Africa and its eastern range extending to Polynesia. It is commonly found in rivers and streams in coastal areas or on islands. C. typus is known to play a role in sediment distribution and shredding leaf litter, manipulating the environment using their pereiopods and setaceous chelae. The species is also an important component of the food web, both as scavengers and as prey items, and is considered a keystone species for the stream ecosystems it inhabits. According to Choy and Marshall, the species can be characterized by a "short, dorsally unarmed rostrum, the presence of epipods on the first four pairs of pereiopods, and the presence of an appendix interna on the endopod of the first pleopod of both sexes." It can be kept in captivity by aquarists as pets.
