More Info
Distribution |
South of Robe, South Australia, to north of Bathurst Island, Northern Territory, and the Coral Sea NE of Cairns, Queensland, to the southern Tasman Sea, Tasmania; also the Christmas Island area in the eastern Indian Ocean, and the Lord Howe Rise and Norfolk Ridge in the Tasman Sea. Elsewhere the species is circumglobal in tropical and temperate latitudes. Inhabits mesopelagic to bathypelagic depths. |
Features |
Postorbital pores 6-17, arranged in a staggered row; Preopercular pores 6-13. Body extremely long, even filamentous, delicate; pectoral fins present; dermal ridges absent. Jaws greatly produced forwards, and typically curving apart, but greatly shortened in mature males. Teeth, minute, in many rows, forming rasp-like surfaces on jaws and vomer. Dorsal-fin origin slightly before or over pectoral-fin base; anus far forwards, under pectoral base; median fins continuous around tail. |
Feeding |
Feeds mostly on crustaceans, especially decapods and euphausids. Snipe eels have minute backward-pointing teeth that prevent their crustacean prey from escaping. |
Remarks |
The jaws of males become shorter as they grow, and they also lose their teeth. |
Etymology |
The species is named scolopaceus in reference to the similarity between the snipe eel jaws to the long bird beak of birds belonging to Scolopax, a genus of long-billed wading birds. |
