Von Vaupel Klein's organ on right endopodal segment 1 and right basal seta of P1. A, anterior, distal up (denticles and pores not drawn; B, right basal seta; C, proximal endopodal segment (showing pores and denticles)
Scale line; short = 50 µm; long = 140 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.

Species Canthocalanus pauper - Distribution map 5Issued from : S.-H. Hsiao, J.-S. Hwang & T.-H. Fang in Crustaceana, 2010, 83 (2). [p.184, Table I].
Copepods collected from the sea around northern Taiwan and from southern East China Sea extending to the Okinawa Trough, to study possible spatial heterogeneity. The content of the same metal shows considerable variation both intra- and inter-specifically. The metal concentrations in males are higher than in females. Copepod metal quota display spatial variation: coastal water > southern East China Sea > Kuroshio water, suggesting that the metal contents of copepods are influenced by the water quality of their marine environment.

The mean female size is1.526 mm (n = 30; SD = 0.1872), and the mean male size is 1.388 mm (n= 30; SD = 0.1843). The size ratio (male : female) is 0.90.
Rem.: Epipelagic.
The presence in the Atlantic needs confirmation.
Oddly, this species, reported by Thompson & Scott (1903) between Marseille and Messine, next between Messine and Port Said, does not seem to be found again in the Mediterranean Sea.
After CB. Wilson (1950, p.184) specimens, including both sexes, were obtained in the surface tow made 5 miles south of Suva Lightship in the Fiji Islands.

Sewell (1914 a, p.194) inclines to regard the branching of the furcal setae merely as an abnormality and not a true variety.
For Itoh (1970 a, fig.2, from co-ordonates) the Itoh's index value from mandibular gnathobase = 460.
Timonin (1971, p.282) considers the trophic interrelations in the equatorial and tropical Indian Ocean, and divides the plankters into 6 trophic groups from the litterature and the results of studies of mouth-parts structure and intestine content. This species is a fine-filter feeder.
