 issued from : T.E. Bowman in Bull. mar. Sc. Gulf Caribb., 1958, 8 (2). [p.119, Fig.1, B, C]. Female (from off Georgia, USA)): B, habitus (dorsal); C, idem (lateral). Nota: Cephalothorax about half as wide as long; with moderately developed dorsal hump. Nn partial suture between head and 1st thoracic segment. A1 reaching beyond caudal rami by about the last four segments.. Distal part of exopod segment 3 of P4 with 12-13 teeth on outer margin.

 issued from : W. Vervoort in Atlantide Report., 1963, 7. [p.102, Fig.5]. Female (from off Ghana): a-b, habitus (lateral and dorsal, respectively) (x88); c, P5 (x375).

 issued from : G.D. Grice in Fish. Bull. Fish and Wildl. Ser., 1962, 61. [p.185, Pl.5, Figs.17-20]. Female (from equatorial Pacific): 17-18, habitus (dorsal and lateral, respectively); 19-20, posterior part of thorax and urosome (dorsal and lateral, respectively). Nota: This species is recognized by the lack of partial suture between the head and 1st thoracic segment and the number of lateral teeth on the distal part of the 3rd exopodal segment of P4.

Distribution map of Acrocalanus andersoni by geographical zones
|
| | | | | | | | |  issued from : T.E. Bowman in Bull. mar. Sc. Gulf Caribb., 1958, 8 (2). [p.122, Fig.3].
Distribution of A. andersoni, data for the 4 cruises combined. combined; T. N. Gill cruises 1-4 (10 Feb.-10 March, 17 April-14 May, 16 July-12 Aug., 17 Oct.-12 Nov.)
Nota: the species is an inhabitant of oceanic waters, and its shoreward distribution is limited by the cooler and less saline Carolinian Coastal water (Bumpus & Pierce, 1955). A. longicornis has a similar distribution, and the two species were often taken in the same net tow. |
| | | | Loc: | | | Angola (Baia Farta), Congo, G. of Guinea, Ivorian shelf, off S Cape Verde Is., off Senegal-Mauritania, Morocco-Mauritania, Canary Is., off Amazon, G. of Mexico, Florida, off S Cape Cod, Natal, Indian, Pacif. (equat.), Pacif. (W equatorial), China Seas (East China Sea, South China Sea), Japan Sea, G. of California, La Paz, Galapagos-Ecuador.
Data from Cornils & Blanco-Bercial (2013): 01°00'S; 09°00'W. | | | | N: | 37 | | | | Lg.: | | | (14) F: 1,12-1,02; M: 1,1; 0,99; (101) F: 1,17-0,95; (180) F: 1,29-1,09; M: 1,20-1,09; (332) F: 1,27; M: 1,12; (414) F: 1,3-1,15; (1112) F: 1,2; 1,3; {F: 0,95-1,30; M: 0,99-1,20} | | | | Rem.: | epipelagic.
For Bowman (1958, p.121) the species of Acrocalanus are most conveniently distinguished by the shape of the cephalothorax in lateral view. | | | Last update : 13/11/2020 | |
