Syngnathoidei is a large, diversesuborder ofsyngnathiform fish. It contains the "long-snouted" members of the order, and its monophyly has been affirmed by phylogenetic studies. The order containspipefish,seahorses,trumpetfish,cornetfish,shrimpfish, andsnipefish.[2][3] They are found in tropical, subtropical and temperate seas, especially in coastal waters around rock and coral reefs and amongsea weed andsea grass beds. However, there are also pelagic species of pipefish and even freshwater species.
This appears to be an ancient suborder, with fossil remains known as early as theLate Cretaceous period.[1]
