Syngnathid
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 fertili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Male Pregnancy
Male pregnancy is the incubation of one or more embryos or fetuses by organisms of the male sex in some species. Most species that reproduce by sexual reproduction are heterogamous—females producing larger gametes (ova) and males producing smaller gametes (sperm). In nearly all animal species, offspring are carried by the female until birth, but in fish of the family Syngnathidae (pipefish, seahorses and the leafy seadragon), males perform that function. In animals The fish family Syngnathidae has the unique characteristic of a highly derived form of male brood care referred to as "male pregnancy". The family is highly diverse, containing around 300 different species of fish. Included in Syngnathidae are seahorses, the pipefish, and the weedy and leafy seadragons. The males of some of these species possess a brood pouch on the trunk or tail; in other species, the eggs are merely attached to the male's trunk or tail when the female lays them.

Alligator Pipefish
The alligator pipefish or double-ended pipefish (''Syngnathoides biaculeatus'') is a species of fish in the family Syngnathidae and is the only species in the monotypic genus '' Syngnathoides''. It is found in shallow water in the tropical and subtropical Indo-Pacific, its range extending from East Africa to northern Australia. This fish lives in habitats of seagrass and seaweed, and hides by positioning itself vertically with its head down amidst the similar-coloured fronds of vegetation. The elongated, well-camouflaged body can reach in length. It feeds by sucking up its prey. Description The alligator pipefish can grow to a length of about though a more typical length is . The narrow head has the snout tipped by a pair of short tentacles and the body is elongated and tetrahedral. The dorsal fin has 38 to 48 soft rays and the anal fins have 4 soft rays. The tail is long and tapering. It is prehensile and lacks a tail fin, being used to anchor the fish to vegetation. The colour ...

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 ...

Brood Pouch (Syngnathidae)
Marsupium is the Latin word for a (brood) pouch in several animal groups: * Pouch (marsupial), in marsupials * Brood pouch (Peracarida), in peracarid crustaceans * Brood pouch (Syngnathidae), in syngnathids such as sea horses * Brood pouch (gastropod), a part of the reproductive system of gastropods The reproductive system of gastropods (slugs and snails) varies greatly from one group to another within this very large and diverse taxonomic class of animals. Their reproductive strategies also vary greatly, see Mating of gastropods.

Syngnathinae
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] |
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 ...
