Abralia redfieldi
Kotaro Tsuchiya and Richard E. YoungIntroduction
A. redfieldi is widely distributed in the Atlantic Ocean. This species is very similar to the Pacific species A. similis, but separable by the larger numbers of arm hooks (13-16 vs. 6-12 in A. similis).
Characteristics
- Tentacle clubs
- Hectocotylus
- Right ventral arm of male hectocotylized.
- Hectocotylus with very large bilobed flap, distal to arm hooks, on dorsal margin and small, more distal flap on ventral margin.
- Eye Photophores
- Five, silvery organs.
- Integumental Photophores
- Ventral mantle and head with scattered arrangement of integumental organs.
- Ventral mantle and head with scattered arrangement of integumental organs.
- Epidermis
- Thick, fragile, and gelatinous.
Comments
A. redfieldi is related with A. similis, and A. omiae in their:- Five monotypic, silvery eye photophores.
- Large, bilobed proximal flap of hectocotylus.
- Small size and thick, gelatinous epidermis.
A. grimpei also resembles the above species but has more than 5 eye photophores.
Distribution
Vertical distribution
One specimen was caught during night by midwater tow at a depth of 100-50m at 10° N, 20° W (Lu & Clarke, 1975)Geographical distribution
Type locality: Off Gun Cay, Bahamas (western North Atlantic).
This species is widely distributed from Nova Scotia (43°N to Argentina (45°S) in the western Atlantic (Nesis, 1982/87) and in the eastern Atlantic it has been taken tropical waters Africa (Lu and Clarke, 1975) and off South Africa at 45°S, 54°W (Lipinski, 1983).
