Syngnathidae
Syngnathidae is a family of fish which includes the seahorses, the pipefishes, and the weedy and leafy sea dragons. The name is derived from Greek, meaning "fused jaw" - syn meaning fused or together, and gnathus meaning jaws. This fused jaw trait is something the entire family has in common.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 the body. The armour gives them a rigid body, so that they can swim by rapidly fanning their fins. As a result, they are relatively slow compared with other fishes, but are able to control their movements with great precision, including hovering in place for extended periods.
