Dolichopteryx rostrata Fukui & Kitagawa, 2006 |
| Family: | Opisthoproctidae (Barreleyes or spookfishes) | |||
| Max. size: | 6.62 cm SL (male/unsexed) | |||
| Environment: | bathypelagic; marine; depth range - 600 m | |||
| Distribution: | Northeast Atlantic: Hebrides Is, | |||
| Diagnosis: | Dorsal soft rays (total): 9-9; Anal soft rays: 8-8; Vertebrae: 41-41. The new species is characterized by the following: an elongate snout and head; small pouchlike eyes; an adipose fin; short dorsal fin base; anal fin base originating under dorsal fin base; a clear longitudinal suborbital brownish band extending forward from behind posterior margin of orbit to snout tip; and 41 (= 26+15) vertebrae. Total fecundity is low; the ovarian eggs number only 473, despite the ovary having developed ova. Ovarian eggs could be clearly subdivided into an 'undeveloped group' (0.1-0.7?mm diameter classes, n?=?405) and a 'developed group' (0.9-1.3?mm classes, n=68), based on their frequency distribution (Ref. 58272). | |||
