Distribution map of Heterorhabdus spinifer by geographical zones
|
| | | | | | | | |  Chart of 1996 | |
| | | | Loc: | | | South Africa (E & W), off NE Tristan da Cunha, Caribbean Sea, Caribbean Colombia, G. of Mexico, off Bermuda (Station "S"), Sargasso Sea, off Delaware, W Medit. (in Kovalev & Shmeleva, 1982, p.84), Natal, S Indian (E-W), S Pacif. tropical (E-W), off NE New Zealand.
Locality type: Caribbean Sea and Gulf of Mexico.
For Park (2000, p.109)The species has a circumglobal distribution. In the Indo-Pacific, the species seems to be restricted mainly to the southern tropical regions, while it occurs widely in the Atlantic. | | | | N: | 9 | | | | Lg.: | | | (88) F: 1,72-1,58; M: 1,72-1,6; (399) F: 1,8; M: 1,75; (824) F: 1,9-1,6; M: 2,02-1,64; {F: 1,58-1,90; M: 1,60-2,02} | | | | Rem.: | epi-meso-bathypelagic. Sargasso Sea: 0-1500 m (Deevey & Brooks, 1977, Station "S");
For park (1970, p.523) this species is related to H. spinifrons (Claus) and H. subspinifrons Tanaka. In anatomical details of appendages, the present species is closely related to H. papilliger (Claus), except for P5 (in spinifer the female has no setae on the 1st endopodal segment, and the male has a characteristic internal projection on the 2nd exopodal segment of the right leg). | | | Last update : 14/06/2022 | |
