Ibacus peronii Leach, 1815 | |
Ibacus peronii, the Balmain bug or butterfly fan lobster, is a species of slipper lobster. It lives in shallow waters around Australia and is the subject of small-scale fishery. It is a flattened, reddish brown animal, up to 23 cm (9 in) long and 14 cm (6 in) wide, with flattened antennae and no claws.
In common with other slipper lobsters, Ibacus peronii has a broad, flattened body and a large carapace. [2] The carapace is reddish brown, [3] and reaches lengths of 2–10 centimetres (0.8–3.9 in), with the whole animal able to reach a length of 23 cm (9 in), [4] and a width of 10–14 cm (3.9–5.5 in). [3] The antennae are also long and broad, and the flattened form of the whole animal allows it to partly penetrate itself in soft substrates. [2] They have five pairs of legs and no claws. Captured animals typically weigh around 120 grams (4.2 oz), but the weight can range from 80 to 200 g (2.8 to 7.1 oz). [3]
Female Ibacus peronii grows faster and reaches larger sizes in comparison to male Ibacus peronii. [5] The size of female Ibacus peronii is significant because there is a linear relationship between the fecundity and the carapace length. [6]
The species is often confused with the Moreton Bay bug, Thenus orientalis, but they can be distinguished by the placement of the eyes: the eyes of I. peronii are near the claws, while those of T. orientalis are at the margin of the legs. [2]
It is found at depths of 20–450 metres (66–1,476 ft) off the coast of Australia from Southport in Queensland to Geraldton in Western Australia. [4] A further population exists in Western Australia from Port Hedland to Broome. [3] A Specimen was found in Port Phillip bay in July 2016.
Ibacus peronii is nocturnal and feeds on algae and small crustaceans. [2] They often spend the daytime buried in sand or mud. [3]
Ibacus peronii is the most commercially important species in the genus Ibacus . [3] Only wild-caught Ibacus peronii are available, although some research into aquaculture is ongoing. [3] The fishery for I. peronii is focussed around New South Wales, where it is mainly caught as bycatch of trawling for fish and prawns. There is a peak in supply in January and February, and the price is highest in areas where it is caught, because of its increased familiarity and popularity there. [3] I. peronii is almost always available at fish markets in Sydney. [4]
The flesh of I. peronii is sometimes reported as tasting of garlic, which makes the species less desirable than the Moreton Bay bug, Thenus orientalis, for cooking. [4] Only the tail contains edible meat. Small individuals yield 30% meat, while larger animals, which have proportionally smaller tails, have lower yields. [3]
The species Ibacus peronii was described by William Elford Leach in 1815, based on material collected by François Péron. Péron had labelled the animal Scyllarus incisus, and had previously called it Scyllarus kingiensis. [7] Although the type locality was given simply as "New Holland" (now Australia), historical records demonstrate that the animal was caught off King Island, in the Bass Strait between Tasmania and the Australian mainland. [7]
Common names used in Australia for Ibacus peronii include Balmain bug, Eastern Balmain bug, [3] butterfly lobster, flapjack, Péron's Ibacus crab, sand crayfish, sand lobster, southern shovel-nosed lobster, prawn killer and squagga, [4] although the last two are not in current use. [8] The named preferred by the Food and Agriculture Organization is butterfly fan lobster. [4] Although it is most widely known as the "Balmain bug", three other species of Ibacus share that name. [8]
The Caridea, commonly known as caridean shrimp or true shrimp, 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.
Spiny lobsters, also known as langustas, langouste, or rock lobsters, are a family (Palinuridae) of about 60 species of achelate crustaceans, in the Decapoda Reptantia. Spiny lobsters are also, especially in Australia, New Zealand, Ireland, South Africa, and The Bahamas, called crayfish, sea crayfish, or crawfish, terms which elsewhere are reserved for freshwater crayfish.
Lobsters are widely fished around the world for their meat. They are often hard to catch in large numbers, but their large size can make them a profitable catch. Although the majority of the targeted species are tropical, the majority of the global catch is in temperate waters.
Slipper lobsters are a family (Scyllaridae) of about 90 species of achelate crustaceans, in the Decapoda clade Reptantia, found in all warm oceans and seas. They are not true lobsters, but are more closely related to spiny lobsters and furry lobsters. Slipper lobsters are instantly recognisable by their enlarged antennae, which project forward from the head as wide plates. All the species of slipper lobsters are edible, and some, such as the Moreton Bay bug and the Balmain bug are of commercial importance.
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.
Thenus orientalis is a species of slipper lobster from the Indian and Pacific oceans.
Metanephrops boschmai, known as the Bight lobster, Bight scampi or Boschma's scampi, is a species of lobster endemic to Western Australia.
Scyllarus arctus is a species of slipper lobster which lives in the Mediterranean Sea and eastern Atlantic Ocean. It is uncommon in British and Irish waters, but a number of English-language vernacular names have been applied, including small European locust lobster, lesser slipper lobster and broad 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.
Scyllarides is a genus of slipper lobsters.
Parribacus japonicus, the Japanese mitten lobster, is a species of slipper lobster. Though the common name for this lobster is the Japanese mitten lobster, it is locally called zōri-ebi (ゾウリエビ) – zōri denoting the Japanese sandal it resembles, and ebi meaning shrimp or lobster.
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.
Arctides is a genus of slipper lobsters, containing three species. The largest of these, A. antipodarum, has a carapace up to 100 millimetres (3.9 in) long, and is found off south-eastern Australia and parts of New Zealand. The other two species are smaller, at up to 70 millimetres (2.8 in) carapace length; A. guineensis is found in an area similar to the Bermuda Triangle; A. regalis is widely distributed in the Indo-Pacific, from the Mascarene Islands to Hawaii and Easter Island.
Arctides guineensis is a species of slipper lobster that lives in the Bermuda Triangle. It is known in Bermuda as the small Spanish lobster, a name which is also favoured by the FAO.
Scyllarides aequinoctialis is a species of slipper lobster that lives in the western Atlantic Ocean from South Carolina to São Paulo State, Brazil, including the Gulf of Mexico, Caribbean Sea and Bermuda. Its common name is Spanish slipper lobster. It grows up to 30 centimetres (12 in) long, with a carapace 12 cm (4.7 in) long. S. aequinoctialis is the type species of the genus Scyllarides, and the first species of slipper lobster to be described from the Western Atlantic.
Scyllarus pygmaeus is a species of slipper lobster that lives in shallow water in the Mediterranean Sea and eastern Atlantic Ocean. It grows to a length of 55 mm (2.2 in), which is too small for it to be fished for food. The juvenile form was first described in 1885, with the description of the adult following in 1888 as a result of the Challenger expedition.
Neoglyphea inopinata is a species of glypheoid lobster, a group thought long extinct before Neoglyphea was discovered. It is a lobster-like animal, up to around 15 centimetres (5.9 in) in length, although without claws. It is only known from 17 specimens, caught at two sites – one at the entrance to Manila Bay in the Philippines, and one in the Timor Sea, north of Australia. Due to the small number of specimens available, little is known about the species, but it appears to live up to five years, with a short larval phase. A second species, previously included in Neoglyphea, is now placed in a separate genus, Laurentaeglyphea.
Ibacus ciliatus is a species of slipper lobster from the north-west Pacific Ocean.
Ibacus alticrenatus is a species of slipper lobster that lives in the waters of Australia and New Zealand.
