Palibythus
''Palibythus magnificus'', sometimes called the musical furry lobster, is a species of furry lobster found in Polynesia. It is generally included in the family Palinuridae, although it has also been separated from that family with the genus ''Palinurellus'' to form the family Synaxidae in the past. Online version''Palibythus magnificus'' The species is known in Samoan as ', a name which also covers the deep-water shrimp ''Heterocarpus laevigatus''. Distribution ''Palibythus'' is only known to occur around Samoa and the Tuamotu Archipelago. It lives at greater depth than ''Palinurellus'' – from – and is slightly larger, at up to in length. All the specimens held in natural history museums stem from the waters of Samoa, with only photos so far known of an animal from the Tuamotu Archipelago that is "almost definitely this species". Sound Like other spiny lobsters (with the exception of the genera ''Jasus'' and '' Projasus''), ''Palibythus'' is capable of making a loud scree ...

Synaxidae
Furry lobsters (sometimes called coral lobsters) are small decapod crustaceans, closely related to the slipper lobsters and spiny lobsters. The antennae are not as enlarged as in spiny and slipper lobsters, and the body is covered in short hairs, hence the name furry lobster. Although previously considered a family in their own right (Synaxidae Spence Bate, 1881), the furry lobsters were subsumed into the family Palinuridae in 1990,. Subsequent molecular phylogenetics studies have confirmed that the furry lobsters genera don't form a natural group and were both nested among the spiny lobster genera in family Palinuridae. The family now includes the two furry lobster genera and ten spiny lobster genera. Taxonomy There are two genera, with three species between them: *''Palinurellus gundlachi'' Von Martens, 1878 – Caribbean furry lobster, found in the Caribbean Sea and the Atlantic coast of South America; named for Juan Gundlach *''Palinurellus wieneckii'' ( De Man, 1881) – ...

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] |
Sister Taxa
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...

Antenna (biology)
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched ...

Rostrum (anatomy)
Rostrum (from Latin ', meaning ''beak'') is a term used in anatomy for a number of phylogenetically unrelated structures in different groups of animals. Invertebrates * In crustaceans, the rostrum is the forward extension of the carapace in front of the eyes. It is generally a rigid structure, but can be connected by a hinged joint, as seen in Leptostraca. * Among insects, the rostrum is the name for the piercing mouthparts of the order Hemiptera as well as those of the snow scorpionflies, among many others. The long snout of weevils is also called a rostrum. * Gastropod molluscs have a rostrum or proboscis. * Cephalopod molluscs have hard beak-like mouthparts referred to as the rostrum.

Invertebrate Taxonomy
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', ...

Palinurus
Palinurus (''Palinūrus''), in Roman mythology and especially Virgil's ''Aeneid'', is the coxswain of Aeneas' ship. Later authors used him as a general type of navigator or guide. Palinurus is an example of human sacrifice; his life is the price for the Trojans landing in Italy. Palinurus in the ''Aeneid'' In Book 3, which tells of the Trojans' wanderings after The Fall of Troy, he is singled out as an experienced navigator. In Book 5, when the Trojans have left Carthage, he advises Aeneas to forestall sailing to Italy and to wait out a terrible storm on Sicily, where they hold the funeral games honoring Aeneas's father, Anchises. After they leave Sicily for Italy, Palinurus, at the helm of Aeneas's ship and leading the fleet, is singled out by Virgil in second person when it becomes clear that he is the one whom the gods will sacrifice to guarantee safe passage to Italy for the Trojans: ''unum pro multis dabitur caput'', "one single life shall be offered to save many."
