Penetopteryx Nanus
''Penetopteryx nanus'', also known as the worm pipefish, is a species of marine fish belonging to the family Syngnathidae. The species can be found in shallow water coral rubble and macroalgae habitats in the Western Atlantic from Providencia Island, Colombia, to the Bahamas and Belize. Reproduction occurs through ovoviviparity Ovoviviparity, ovovivipary, ovivipary, or aplacental viviparity is a term used as a "bridging" form of reproduction between egg-laying oviparous and live-bearing viviparous reproduction. Ovoviviparous animals possess embryos that develop insi ... in which the males brood eggs before giving live birth. ''Penetopteryx nanus'' are typically 3-6 millimeters when born and can reach up to recorded lengths of 3.17 centimeters in adulthood. In their larval state, ''Penetopteryx nanus'' have well-developed fins, but these are lost in adulthood.

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] |
