Snout cylindrical. Pectoral and caudal fins present. With 13-15 bony plates between head and dorsal fin (Ref. 35388). Caudal fin somewhat angulous, diamond shaped (Ref. 59043).
Body shape (shape guide): eel-like.
Coastal and estuarine waters (Ref. 126547); often found on sandy shores among floating or attached seaweeds (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. Young are sometimes caught pelagically in the North Sea (Ref. 35388).
