Acentronura
'' Acentronura '' is a genus of pygmy pipehorse native to the Indian and Pacific oceans. The name is derived from the Greek ακεντρονουρα, or ''a-kentron-oura'', and refers to the lack of a sting on the tail. Species There are currently two recognized species in this genus, several previous members having been moved to the genera '' Amphelikturus'' and ''Idiotropiscis'': * ''Acentronura breviperula'' Fraser-Brunner & Whitley, 1949 (Dwarf pipehorse) * ''Acentronura gracilissima'' (Temminck & Schlegel, 1850) (Bastard seahorse) * ''Acentronura tentaculata'' ( Günther, 1870) (Shortpouch pygmy pipehorse) Distribution ''Acentronura'' species are mainly found in shallow tropical and subtropical waters of the Indo-west Pacific and the Red Sea. When fully grown they vary from in length, with the average maximal size being about . They are small, secretive, and very well camouflaged, and are therefore quite rarely seen; for this reason, some species may be more common tha ...

Acentronura Tentaculata
''Acentronura tentaculata'', the shortpouch pygmy pipehorse , northern little pipehorse, or dwarf pipehorse, is a species of pygmy pipehorse from the family Syngnathidae. The status of this species is debated and '' Acentronura breviperula'' is considered to be subsumed within this species by some authorities. The exact distribution of this species may be as wide as the western Indo-Pacific region from East Africa to New Caledonia and the northern Great Barrier Reef. Other authorities however describe ''Acentronura tentaculata'' as being endemic to the Red Sea. References tentaculata Tentaculata is a class of comb jellies. The common feature of this class is a pair of long, feathery, contractile tentacles, which can be retracted into specialised ciliated sheaths. In some species, the primary tentacles are reduced and they h ... Fish of the Red Sea Fish described in 1870 Taxa named by Albert Günther {{Syngnathiformes-stub ...

Acentronura Breviperula
''Acentronura breviperula'', also known as the shortpouch pygmy pipehorse, dwarf pipehorse and northern little pipehorse, is a species of pygmy pipehorse, a member of the family Syngnathidae, the seahorses and pipefishes. It occurs in the Indo-Pacific region from the eastern Andaman Sea, through the Malay Archipelago to the Western Pacific as far east as New Guinea and the northern Great Barrier Reef. It is a small, drab-coloured pipehorse which is very well camouflaged among sandy and silty habitats, although it is usually found on substrates of coral rubble or in areas of sparse algal growth. It has a prehensile tail similar to that of a seahorse but it lacks an angled head and swims with its body held in a horizontal position. It is normally recorded in pairs and they typically use their prehensile tails to grip onto pieces of algae or debris. It is a carnivorous species which feeds on small invertebrates. Like other syngnathids it is ovoviviparous and the males hold the dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acentronura Gracilissima
''Acentronura gracilissima'', the bastard seahorse, is a species of pygmy pipehorse from the coastal waters of Japan and Vietnam, it is expected to occur elsewhere but reports in other areas need to be confirmed. It occurs on rock and algae reefs downto depths of where it feeds on mysids, small crabs, fish larvae and probably also on harpacticoid copepods and gammarid shrimps as recorded in other species in the family Syngnathidae The Syngnathidae is a family of fish which includes seahorses, pipefishes, and seadragons (''Phycodurus'' and ''Phyllopteryx''). The name is derived from grc, σύν (), meaning "together", and (), meaning "jaw". The fused jaw is one of the tra ....

Gilbert Percy Whitley
Gilbert Percy Whitley (9 June 1903 – 18 July 1975) was a British-born Australian ichthyologist and malacologist who was Curator of Fishes at the Australian Museum in Sydney for about 40 years. He was born at Swaythling, Southampton, England, and was educated at King Edward VI School, Southampton and the Royal Naval College, Osborne. Whitley migrated with his family to Sydney in 1921 and he joined the staff of the Australian Museum in 1922 while studying zoology at Sydney Technical College and the University of Sydney. In 1925 he was formally appointed Ichthyologist (later Curator of Fishes) at the Museum, a position he held until retirement in 1964. During his term of office he doubled the size of the ichthyological collection to 37,000 specimens through many collecting expeditions. Whitley was also a major force in the Royal Zoological Society of New South Wales, of which he was made a Fellow in 1934 and where he served as president during 1940–41, 1959–60 and 1973–74. ...

Seahorse
A seahorse (also written ''sea-horse'' and ''sea horse'') is any of 46 species of small marine fish in the genus ''Hippocampus''. "Hippocampus" comes from the Ancient Greek (), itself from () meaning "horse" and () meaning "sea monster" or "sea animal". Having a head and neck suggestive of a horse, seahorses also feature segmented bony armour, an upright posture and a curled prehensile tail. Along with the pipefishes and seadragons (''Phycodurus'' and ''Phyllopteryx'') they form the family Syngnathidae. Habitat Seahorses are mainly found in shallow tropical and temperate salt water throughout the world, from about 45°S to 45°N. They live in sheltered areas such as seagrass beds, estuaries, coral reefs, and mangroves. Four species are found in Pacific waters from North America to South America. In the Atlantic, ''Hippocampus erectus'' ranges from Nova Scotia to Uruguay. ''Hippocampus zosterae, H. zosterae'', known as the dwarf seahorse, is found in the Bahamas. Colonies hav ...

Pipefish
Pipefishes or pipe-fishes (Syngnathinae) are a subfamily of small fishes, which, together with the seahorses and seadragons (''Phycodurus'' and ''Phyllopteryx''), form the family Syngnathidae. Description Pipefish look like straight-bodied seahorses with tiny mouths. The name is derived from the peculiar form of the snout, which is like a long tube, ending in a narrow and small mouth which opens upwards and is toothless. The body and tail are long, thin, and snake-like. They each have a highly modified skeleton formed into armored plating. This dermal skeleton has several longitudinal ridges, so a vertical section through the body looks angular, not round or oval as in the majority of other fishes. A dorsal fin is always present, and is the principal (in some species, the only) organ of locomotion. The ventral fins are consistently absent, and the other fins may or may not be developed. The gill openings are extremely small and placed near the upper posterior angle of the gill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Idiotropiscis
''Idiotropiscis'' is a genus of pygmy pipehorse endemic to Australia. They are commonly called pygmy pipehorses due to their small size. Species There are currently three recognized species in this genus: * '' Idiotropiscis australe'' ( Waite & Hale Hale may refer to: Places Australia *Hale, Northern Territory, a locality *Hale River, in southeastern Northern Territory Canada *Hale, Ontario, in Algoma District United Kingdom * Hale, Cumbria, a hamlet near Beetham, Cumbria *Hale, Greater Man ..., 1921) (Southern little pipehorse) * '' Idiotropiscis larsonae'' ( C.

Syngnathidae
The Syngnathidae is a family of fish which includes seahorses, pipefishes, and seadragons (''Phycodurus'' and ''Phyllopteryx''). The name is derived from grc, σύν (), meaning "together", and (), meaning "jaw". The fused jaw is one of the traits that the entire family have in common. Description and biology Syngnathids are found in temperate and tropical seas across the world. Most species inhabit shallow, coastal waters, but a few are known from the open ocean, especially in association with sargassum mats. They are characterised by their elongated snouts, fused jaws, the absence of pelvic fins, and by thick plates of bony armour covering their bodies. The armour gives them a rigid body, so they swim by rapidly fanning their fins. As a result, they are relatively slow compared with other fish but are able to control their movements with great precision, including hovering in place for extended periods. Uniquely, after syngnathid females lay their eggs, the male then fertiliz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Algae
Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (class), and mostly consist of multicellular, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats but relatively rare in freshwaters. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. The red algae form a distinct group characterized by having eukaryotic cells without flagella and centrioles, chloroplasts that l ...

Algae
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around thei ...
