Morphology | Morphometrics
Snout is compressed and taller than the eye diameter (Ref. 35388) and anterior trunk rings not fused ventrally (Ref. 59043).
Eastern Atlantic: Vardø, Norway, Baltic Sea and the British Isles to Morocco. Also throughout the Mediterranean, Black Sea and Sea of Azov. Record off Ghana is still questionable (Ref. 4509).
Usually found along the coasts and estuaries at a temperature range of 8° to 24°C (Ref. 4944). Often associated with Zostera or other vegetation (Ref. 6733). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Spawns in summer (Ref. 35388).
