The Greater pipefish, (Syngnathus acus, Linnaeus, 1758), is a pipefish of the family Syngnathidae. It is a seawater fish and the type specimen of the genus Syngnathus.
The genus name Syngnathus derives from the Greek, syn, symphysis meaning grown together and gnathos meaning jaw. The Latin species name acus means needle.
The Greater pipefish has a long segmented armoured body, angular in cross section and stretching up 45 cm long with its stiff appearance. It ranges a color brown to green in with broad alternating light and dark hue along it. Its customized by a long snout with mouth on end and a slight hump on the top of the body just behind the eyes.
The fish is generally 33 cm to 35 cm in length with a reported maximum length of 47 cm. They are almost square in each segment of the body, and known to feel rigid when handled. The Greater pipefish has distinctive body rings which are a sandy brown with darker bars covering his body in between.
The anatomy of fish vary through the sex. The top third of the females belly is deep (when egg bound), twice the breadth of the lower two thirds below the vent. The male is the "tailing" with the twin folds below the vent. The folds of the skin make the middle third and during the "brooding" of the young they swell in size until the young are released from the pouch (at a size of 22 mm to 35 mm).
These fishes feed on live mysids and small prawns. They are ovoviviparous and reproduce usually theree times each year. A few females deposit partial clutches under the tail into the male’s brood pouch, that may contain up to 400 eggs.
The Greater Pipefish is found all around the British Isles and is regularly found in the Mediterranean Sea.
These fishes are common on southerly and westerly coasts in a variety of habitats, often amongst seaweeds and seagrass.
