Scyllaridae
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 (''Ibacus peronii'') are of commercial importance. Description Slipper lobsters have six segments in their heads and eight segments in the thorax, which are collectively covered in a thick carapace. The six segments of the abdomen each bear a pair of pleopods, while the thoracic appendages are either walking legs or maxillipeds. The head segments bear various mouthparts and two pairs of antennae. The first antennae, or ''antennules'', are held on a long flexible stalk, and are used for sensing the env ...

Achelata
The Achelata is an infra-order of the decapod crustaceans, holding the spiny lobsters, slipper lobsters and their fossil relatives. Description The name "Achelata" derives from the fact that all the members of this group lack the chelae (claws) that are found on almost all other decapods (from the Ancient Greek , = "not", , = "claw"). They are further united by the great enlargement of the second antennae, by the special "phyllosoma" form of the larva, and by a number of other characters. Classification and fossil record The infraorder Achelata belongs to the group Reptantia, which consists of the walking/crawling decapods (lobsters and crabs). The cladogram below shows Achelata's placement within the larger order Decapoda, from analysis by Wolfe ''et al.'', 2019. Achelata contains the spiny lobsters (Palinuridae), the slipper lobsters (Scyllaridae) and the furry lobsters (Synaxidae, now usually included in Palinuridae), as well as two extinct families, Cancrinidae a ...

Scyllarus Pygmaeus
''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 , which is too small for it to be fished for. The juvenile form was first described in 1885, with the description of the adult following in 1888 as a result of the ''Challenger'' expedition. Description ''S. pygmaeus'' is the smallest slipper lobster species, with a carapace length of for females, and for males. The total body length can reach , but is typically less than . Its small size precludes ''S. pygmaeus'' from being a target for fisheries. The body of ''S. pygmaeus'' is "pale brownish or pinkish with patches of darker hairs". ''S. pygmaeus'' resembles a young individual of ''Scyllarus arctus'', with which it occurs in sympatry. The two species can be distinguished by a suite of characters: *The anterior part of the abdominal tergites have a groove lined with hairs in ''S. pygmaeus'' but not in ''S. arctus ...

Scyllarides Haanii
''Scyllarides haanii'', the Aesop slipper lobster, is a marine decapod crustean in the family Scyllaridae. Other common names include the humpbacked slipper lobster and the ridgeback slipper lobster. Description ''Scyllarides haanii'' can grow to a maximum body length of but commonly range between in length. It is believed to be the largest of the ''Scyllarides'' species. It is a solitary species that shelters during the day and forages at night, primarily on a diet of bivalves. Distribution and habitat ''Scyllarides haanii'' is a wide-ranging benthic species but nowhere abundant, and uncommon in some places. It is native to the Indo-Pacific region and known to occur in the eastern and western Indian Ocean and throughout the Pacific Ocean. It is likely its distribution is larger than indicated in population assessments from 2013 and earlier. ''Scyllarides haanii'' inhabits coral reefs and rocky bottoms in relatively warm coastal waters in winter to early spring, and migra ...

Scyllarides Latus
''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 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. Distribution ''Scyllarus latus'' is found along most of the coast of the Mediterranean Sea (one exception being the northern Adriatic Sea), and in parts of the eastern Atlantic Ocean from near Lisbon in Portugal south to Senegal, includi ...

Ibacus Peronii
''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 long and wide, with flattened antennae and no claws. Description In common with other slipper lobsters, ''Ibacus peronii'' has a broad, flattened body and a large carapace. The carapace is reddish brown, and reaches lengths of , with the whole animal able to reach a length of , and a width of . The antennae are also long and broad, and the flattened form of the whole animal allows it to partly penetrate itself in soft substrates. There are huge claws on the eight pairs of legs. Captured animals typically weigh around , but the weight can range from . Female ''Ibacus peronii'' grows faster and reaches larger sizes in comparison to male ''Ibacus peronii''. The size of female ''Ibacus peronii'' is significant because there is a linear relationship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiny Lobster
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 ("kreef" in South Africa), terms which elsewhere are reserved for freshwater crayfish. Classification The furry lobsters (''e.g.'' ''Palinurellus'') were previously separated into a family of their own, the Synaxidae, but are usually considered members of the Palinuridae. The slipper lobsters (Scyllaridae) are their next-closest relatives, and these two or three families make up the Achelata. Genera of spiny lobsters include ''Palinurus'' and a number of anagrams thereof: ''Panulirus'', ''Linuparus'', ''etc.'' (Palinurus was a helmsman in Virgil's ''Æneid''.) In total, 12 extant genera are recognised, containing around 60 living species: *''Jasus'' Parker, 1883 * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Faunal Directory
The Australian Faunal Directory (AFD) is an online catalogue of taxonomic and biological information on all animal species known to occur within Australia. It is a program of the Department of Climate Change, Energy, the Environment and Water of the Government of Australia. By May 12, 2021, the Australian Faunal Directory has collected information about 126,442 species and subspecies In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species .... It includes the data from the discontinued ''Zoological Catalogue of Australia'' and is regularly updated. Started in the 1980s, it set a goal to compile a "list of all Australian fauna including terrestrial vertebrates, ants and marine fauna" and create an "Australian biotaxonomic information system".''Commonwealth Record'', Volume 5, Issues 26-34, p. 1 ...

Continental Shelf
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an ''insular shelf''. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf. Under the United Nations Convention on the Law of the Sea, the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the shores of a par ...

Appendage
An appendage (or outgrowth) is an external body part, or natural prolongation, that protrudes from an organism's body. In arthropods, an appendage refers to any of the homologous body parts that may extend from a body segment, including antennae, mouthparts (including mandibles, maxillae and maxillipeds), gills, locomotor legs ( pereiopods for walking, and pleopods for swimming), sexual organs (gonopods), and parts of the tail (uropods). Typically, each body segment carries one pair of appendages. An appendage which is modified to assist in feeding is known as a maxilliped or gnathopod. In vertebrates, an appendage can refer to a locomotor part such as a tail, fins on a fish, limbs (legs, flippers or wings) on a tetrapod; exposed sex organ; defensive parts such as horns and antlers; or sensory organs such as auricles, proboscis ( trunk and snout) and barbels. Appendages may become ''uniramous'', as in insects and centipedes, where each appendage comprises a single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mollusca
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.
