 issued from : J.G. Greenwood in Proc. R. Soc. Qd, 1978, 89. [p.8, Fig.3]. Female (from Moreton Bay, E Australia): a, urosome (lateral left side); b, idem (ventral); c, P5. Male: d, posterior part of prosome and urospme (dorsal); e, genital and 2nd urosomal segments (dorsal); f, Mx1; g, P5. Nota: Basipodal segment 2 of female P5 with single seta on each leg; this not figured by Sewell (1912) probably because broken during dissection. Female characteristics (from Bradford-Grieve, 1999 b, p.163): - Posterior metasome corners each terminate in a short spine. - Genital segment symmetrical in dorsal view and globular in shape, with a well-marked genital swelling. - Urosomal segment 2 is produced ventrally in midline into a short spine which is half the length of genital segment. - Caudal rami about twice as long as broad, slightly asymmetrical, that on right being slightly broader than on left. - A1 23-segmented. Mx2 basipod 2 with proximal spine longer and much stouter than distal spine. - P5 segment 3 slightly curved inwards with 2 setae on inner margin, with 3 outer edge spines on distal half of segment; these external spines are blunt and pigmented on left side and sharp and devoid of pigment on the right. Male characteristics (from Bradford-Grieve, 1999 b, p.165) : - Posterior metasome symmetrical, tip of right process does not reach beyond midpoint of genital segment. - Genital segment produced into a toothed tubercle on right side. - Urosomal segment 2 with a patch of small spines near posterior end. - Left A1 23-segmented and extends to posterior border of metasome. - Mx2 segment 2 with 3 short spines. - Left P5 segment 3 is produced at outer distal angle into a short stout pigmented tooth-like process which is divided into 3 blunt points, segment 4 is elongate and narrow with 3 terminal small spines.

 issued from : J. Wickstead in J. Anim. Ecol., 1959, 28. [p.70, Fig.1]. a-b, examples of characteristic attitudes of Candacia bradyi (from Singapore region) affixed to a chaetognath; c, Mx2 of male. Nota: Males and females Candacia bradyi were affixed to a Sagitta enflata, Sagitta pulchra, Sagitta planctonis, to a ctenophore and juvenile Eucalanus (= Subeucalanus) subcrassus, Paracalanus aculeatus, and to an actinotrocha larva of Phoronis. Therefore 73 % were affixed to a chaetognath and 62 % were affixed to a Sagitta enflata. There were no examples of more than 1 copepod being affixed to a simple chaetognath in these samples. The analysis of two samples shows that, in the first haul about 1.1 % of the chaetognaths were attacked by this species copepod, and in the second haul 0.35 %.
