Syngnathiformes


The Syngnathiformes are an order of the bony fish, with the individual families showing strong differences. A total of about 260 species belong to the Syngnathiformes, which are separated into seven families.

They are widespread throughout the world, but they prefer to live near the seabed in vicinity of the coast. Seahorses, for example, hang on different plants, while trumpet fish are mostly found near caves, boulders, canyons and crevices.

Anatomy

Species of Syngnathiformes differ greatly from each other and also from other fish groups. They usually have a slender body with bone plates in the skin. Much of the species lack the pelvic fins or ribs. The three to six vertebrae, which are in front, are often lengthened. Apart from mullets, flying gurnards and Bulbonaricus, they have a pointed nose, mainly a tube-shaped pipette snout. They can suck their prey. Mostly they are toothless or have only very small teeth. The lacrimal bone is often the only bone around the eyehole. Accordingly, the remaining bones of the orbit are absent.
