Species Candacia falcifera - Plate 1 of morphological figuresissued from : G.P. Farran in British Antarctic (\"Terra Nova\") Expedition, 1910. Natural History Reports. Zoology. Vol. VIII. Crustacea, 1929. [p.271, Fig.28].
Female: a, habitus (dorsal view); b, distal part of cephalosome and urosome (dorsal view); c, Mx2; d, fifth foot.
Male: e, distal part of prosome and urosome (dorsal view); f, feeth feet.

Species Candacia falcifera - Plate 2 of morphological figuresIssued from : C. Razouls in Ann. Inst. océanogr., Paris, 1994, 70 (1). [p.176]. Caractéristiques morphologiques de Candacia falcifera femelle et mâle adultes.
Terminologie et abbréviations: voir à Calanus propinquus.

Nota: Cette espèce est proche de C. longimana. La présence caractéristique d'une coloration noire aux extrémités des pattes natatoires ne semble pas toujours assurée.

Species Candacia falcifera - Distribution map 4issued from : W. Vervoort in B.A.N.Z. Antarctic Reseach Expedition, Reports - Ser. B, Vol. III, 1957 [Fig.132]
Chart showing the geographical distribution in the seas surrounding the Antarctic continent.
Nota: In this chart the area frequented by whaling vessels has been hatched. The Antarctic circle (66°.5 S) has been drawn as a broken line. The numbers I to VI refer to the sectors into which the Antarctic seas are divided according to Mackintosh (1942) (after Vervoort, 1951).
Species Candacia falcifera - Distribution map 5Issued from : E.T. Park & F.D. Ferrari in A selection from Smithsonian at the Poles Contributions to International Polar year. I. Krupnik, M.A. Lang and S.E. Miller, eds., Publs. by Smithsonian Institution Scholarly Press, Washington DC., 2009. [p.167, Fig.2.]
Distribution of selected pelagic calanoids Candacia falcifera of the Southern Ocean and the closest relative in the subarctic region of the Arctic Ocean.
Antarct. (Peninsula, SW Atlant., Weddell Sea, South Georgia, SE Atlant., Indian, SW Pacif.), Atlant. tropical (11°N, 37°W) (in Wilson, 1942 a, p.31, 175), Sargasso Sea : off E Cape Cod (42°N, 64°30'W, in Harding, 1974), Greenland (Davis Strait) (in/em> Jespersen, 1934)
N: 11 (Antarct.: 8; Atlant. N: 3)
(25) F: 3,92; (31) F: 3,91; (35) F: 3,7; M: 3,5-3,33; (49) M: 3,8-3,3; {F: 3,70-3,92; M: 3,30-3,80}

The mean female size is 3.843 mm (n = 3; SD = 0.1242), and the mean male size is 3.483 mm (n = 4; SD = 0.2293). The size ratio (male : female) is about 0.91.
Rem.: Meso-bathypelagic.
Sampling depth (Antarct.) : 300-1000 m. In vertical tow 2000-1000 m (Harding, 1974).
The presence of this species in the north Atlantic needs confirmation.
