Eastern Atlantic: Norway, Faroes and British Isles to Western Sahara, Senegambia, and from Namibia to Cape of Good Hope and northward to the coast of Zululand in the western Indian Ocean (Ref. 4127). Also throughout the Mediterranean, Aegean and Black seas. Despite literature records, occurrence in the Indo-Pacific outside South African waters lacks conclusive evidence (Ref. 4281).

Maturity: Lm ?, range 7 - 25.6 cm

Descrição breve Morfologia | Morfometria

Espinhos dorsais (total): 0; Raios dorsais moles (total): 33-42; Espinhos anais 0; Raios anais moles: 3. Light greenish to dark brown in color with variable markings (Ref. 4281). Snout cylindrical, equal to or less than eye diameter. With 18 - 19 body rings between head and dorsal fin (Ref. 35388). The snake pipefish (Entelurus aequoreus) is distinguished by the lack of pectoral and anal fins (Ref. 88171). An elongated bump on top of head behind eye (Ref. 59043).

Biologia     Glossário (ex. epibenthic)

Found in coastal and estuarine waters to depths of at least 110 m (Ref. 4281); on sand, mud and rough bottoms. Common amongst algae and eel-grass (Zostera) (Refs. 4146, 6733, 88187). Feeds mainly on small crustaceans (Ref. 85544).

Life cycle and mating behavior Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

Ovoviviparous; reproducing on average 3 times each year (Ref. 89328). Several females depositing partial clutches to a male’s brood pouch under the tail (Refs. 205, 31201). Up to 400 eggs may be found in a single pouch (Ref. 89329). Brooding males occur mainly between May and July (Refs. 31201, 58137). During the breeding season, both males and females were observed to remain low amongst the seagrass in one meadow (Ref. 31201). Gestation period lasts about 5 weeks and size at birth is 1.7- 3.5 cm (Refs. 58137, 88187, 89330). Aquarium experiments have shown that new born young are benthic, remaining close to the bottom Ref. 89330).
