экология
морской; солоноватоводный демерсальный; немигрирующий (Ref. 88171); пределы глубины 0 - 110 m (Ref. 4281), usually 3 - 15 m (Ref. 126547). Subtropical; 71°N - 35°S, 19°W - 42°E
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).
Length at first maturity / Size / Вес / Возраст
Maturity: Lm 16.3, range 7 - 25.6 cm
Max length : 50.0 cm TL самец/пол неопределен; (Ref. 35388)
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 33 - 42; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 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).
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). It is parasitised by the monogenean Gyrodactylus eyipayipi on the body surface, inside the flute and male brood pouch (Ref. 124059).
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).
