Staves se: 
The abdomen of the female of this species is composed of two segments. The genital 
segment is narrowly ovate in outline. The furcal joints are two and a half times the length 
of the anal segment. 
Corycaeus danae has been recorded from the Indian and Pacific Oceans.

One specimen was found in the plankton collected at the following four stations. 
Stat. 50. — Stat. 118 (HENSEN vertical net, 900 metres to surface). — Stat. 185 HENSEN 
vertical net, 1536 metres to surface). — Stat. 271. 
The abdomen of the female of this Corycaews is composed of one segment. The 
segment is much contracted in front, considerably inflated in the middle, and then slopes 
evenly to the rather narrow distal end. The furcal joints are moderately long and slender, and 
are equal to fully half the length of the abdomen. 
Corycaeus elongatus has been recorded from the Atlantic, Indian and Pacific Oceans, 
and from the Mediterranean.
