Syngnathus typhle Linnaeus, 1758

Body Shape and Cross-section

The broadnosed pipefish (Syngnathus typhle Linnaeus, 1758) is a slender, elongated fish with a hexagonal cross-section. This feature sets it apart from its more thread-like relative, the straightnose pipefish (Nerophis ophidion), which has a circular cross-section.

Body Covering

The entire body surface of the broadnosed pipefish is covered in small bony plates.

Head and Snout Morphology

Its head has a similar shape to that of a seahorse, with a long, laterally flattened snout and an obliquely sloping mouth.

Caudal Fin Structure

Unlike the straightnose pipefish, the broadnosed pipefish has a fan-shaped caudal fin.

Coloration

Its general body color is greenish, often marked with various shades of darker mottling, and its belly is yellow.

Size

On average, this species grows to between 15 and 20 cm (6 to 8 inches) long, with a maximum recorded length of 25 cm (10 inches).

Native Range

The broadnosed pipefish is native to the Eastern Atlantic, Mediterranean Sea, Black Sea, and Sea of Azov.

Distribution Extent

Its distribution range stretches from Vardø, Norway, down to Morocco.

Depth Range

It can be found at depths of up to around 20 m (66 ft).
