Syngnathoidei

Syngnathoidei is a large, diverse suborder of syngnathiform fish. It contains the "long-snouted" members of the order, and its monophyly has been affirmed by phylogenetic studies. The order contains pipefish, seahorses, trumpetfish, cornetfish, shrimpfish, and snipefish. They are found in tropical, subtropical and temperate seas, especially in coastal waters around rock and coral reefs and among sea weed and sea grass beds. However, there are also pelagic species of pipefish and even freshwater species.

Fistularioides (meaning "Fistularia-like") is an extinct genus of prehistoric marine syngnathiform fish that lived during the Early Eocene of Europe. It is known from two species, F. veronensis Blot, 1980 and F. phyllolepis Blot, 1980 from the Monte Bolca site of Italy. left|thumb|Closeup of skull As its name suggests, it superficially resembled and was related to the cornetfishes, though it belonged to its own extinct family, the Fistularioididae. It is one of two known genera from this family, alongside Pseudosyngnathus from the same locality.
