Carte de distribution de Gaetanus robustus par zones géographiques
|
| | | | | | | Loc: | | | off Tristan da Cunha E, off W Canary Is., Azores, Sargasso Sea, Station "S" (32°10'N, 64°30'W), Davis Strait, off W Ireland, ? W Indian, Japan (Izu,) NE, Kuril-Kamchatka, Bering Sea, S Aleutian Basin, S Aleutian Is., Vancouver Is., W Baja California , S Pacif., off Juan Fernandez Is., Chile.
Type locality: N Atlantic (off Azores Islands) | | | | N: | 25 | | | | Lg.: | | | (1) F: 8; (10) F: 8-7,5; (22) F: 9-7,5; M: 7; (37) F: 9,2-7,5; M: 7; (70) F: 9,1-8,4; (113) F: 9,65-8,95; {F: 7,50-9,65; M: 7,00} | | | | Rem.: | méso-abyssopélagique.
Grice & Hulsemann (1967, p.24) ne font pas état, stricto sensu, de l’identification de femelles, d’où un doute concernant la présence de cette espèce dans l’Indien.
