Espèce Cosmocalanus caroli - Planche 1 de figures morphologiquesissued from : W. Giesbrecht in Fauna Flora Golf. Neapel, 1892, 19. [Taf.8, Fig.36].
Male: 36, right P5.

Male: terminal portion of left P5.


Espèce Cosmocalanus caroli - Planche 3 de figures morphologiquesIssued from : C.B. Wilson in U.S. natn. Mus., Bull. 100, 14 (4), 1950. [Pl. 19, figs.252-255]. As Undinula caroli.
Female (with doubt): 252-253, habitus (dorsal and lateral, respectively); 254, last thoracic segment and first three abdominal segments.
Posterior corners of the last thoracic segment asymmetrical, the one of the left reaching the distal margin of the genital segment, closely appressed to the latter, and smoothly rounded at its tip, the one on the right not reaching the center of the genital segment and inclined outward away from it.
The urosome is the same width throughout, the anal segment fully as wide as the genital segment. The latter is as thick dorsoventrally as it is long and has no dorsal posterior spine.
The short setae on each caudal ramus are less than 1/6 as long as the longest one

Male: 255, P5.


Espèce Cosmocalanus caroli - Planche 4 de figures morphologiquesIssued from : J.A. Fornshell & F.D. Ferrari in Crustaceana, 2014, 87 (1). [p.109, Fig.1, A-C].
Von Vaupel Klein's organ on right endopodal segment 1 and right basal seta of P1. A, anterior, distal up; B, right basal seta; C, proximal endopodal segment (showing denticles and pores, ventral seta noted)
Scale line; short = 25 µm; long = 95 µm.

The Von Vaupel Klein organ is an association (srtucture) of the distal seta from basis and the proximal endopodal segment of P1.
This structure shows significant variability among many gymnoplean copepods, in the shape of the distodorsal corner of the proximal endopodal segment, presence and location of denticles on the anterior face of the segment, presence and size of denticles along the distal margin of the segment , number of pores on the segment, shape of the seta that originates on the basis, and the morphology of the basis at the origin of the seta.
The function of this complex structure is not known.
