For the authors: Nannocalanus minor barcodes form a cluster comprising 3 clades in both the tree-based and TCS analysis. The sequence variation did not show any geographical pattern; all 3 clades contained sequences from the NW Atlantic and in some cases were found in the same sample.
Cluster A included a number of individuals with identical sequences collected from the NE and SE Atlantic.
Within each clade, individuals differed by < 1.5% on average, differences ranged from 9.2-14.3%.
Morphological analyses of 2 females from Clade A and B, respectively indicate different numbers of teeth on the inner edge of the basipodite 1 of P5: the Clade A individual showed 11 denticles, compared to 16 for Clade B.
Individual variability is known to be high for this character, and either of the 2 described Nannocalanus species may exhibit 16 teeth. However, 11 teeth on the P5 basipodite 1 is outside the known range for this character for N. minor sensu stricto, suggesting potential reproductive isolation among the 3 Clades, which may be sympatric, cryptic species.

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, pores and 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.

Distribution map of Nannocalanus minor by geographical zones
Species Nannocalanus minor - Distribution map 4issued from : T.S.K. Björnberg in Bol. Inst. Oceanogr., Sao Paulo, 1963, XIII (1). [p.12, Fig.2].
Probability of occurrence of Nannocalanus minor in different environments.
T: Tropical waters (above 36.00 p.1000 salinity and above 20°C temperature); SST: Surface subtropical waters (salinity around 36 p.1000 and temperature 18°C or less); DST: Deeper shelf waters (salinity between 34 and 36, temperature under 20°C p.1000); SS: Surface shelf waters (same salinity and temperature above 20°C);
C: coastal waters with low salinity and variable temperature.

In each column no shading means no probability of finding the species in the samples from this environment; horizontal shading indicates the probability of finding the sepecies in percentages less than one in samples from this environment; cross shading indicates the probability of finding it in percentages higher than one and black shading represents the probability of finding it in the largest percentages of the total number of copepods.

A negative slope indicates a period of below-average anomalies; a positive slope indicates a period of above-average anomalies. Abrupt changes in slope indicate step changes. Step changes are marked with arrows (downward -pointing for decreases).
The October 1966 cruise (prior to the increase in sampling depth), March 1976 cruise (prior to the 1976-77 climatic regime shift), and October 1988 cruise (prior to the hypothesized 1989 climatic regime shift) are marked with vertical lines.

Species Nannocalanus minor - Distribution map 16Issued from : C.B. Miller in Biological Oceanography, Blackwell Publishing, 2005. [p.363, Fig. 16.16 (c)]. After Dessier & Donguy, 1987.
Time series of abundance estimates for Calanus minor (= Nannocalanus minor) species sampled along the Pacific equator from passenger liner on a regular schedule.
Miller underlines that serial abundance for this species from the equator to 2°N shows strong seasonality and dramatic reduction during the 1982-1983 El Niño (with a a sharp reduction of nitrate). A long list of other species also nearly vanished in that event. At least the stocks of hebivorous species rebounded immediately in 1984 (see E. rimana, a predator).

For female in Ikeda & al. (2001) the respiration rate (µl O2 h-1 ind-1) was 0.21 ± 0.01 (40 µg) in the tropical Pacific Ocean.

Relationship between individual ETS activities and individual respiration rates; mean ETS activities with standard deviations are plotted again mean respiration rates (Cf. in Calanoides natalis. The letter besides each point identifies the associated species in Table 1 (c) for this species) in the same authors.
Cf. Table 1: Dry mass, individual respiration rate and ETS activity.
For Ikeda & al. (2001) the female respiration rate at 26.9°C were 0.21 ±0.01 µl O2 h ind-1 (DM: 40 µg) in the Tropical Pacific Ocean.

Tanaka (1960, p.14) found the species at two stations in the Indian Ocean (18°54'S, 60°39'E and 35°09'S , 20°13'E).
For Vervoort (1963 b, p.81), all the specimens from the Atlantide Expedition seems to agree with Sewell's description of N. minor forma major, though the variations in length are fairly wide.

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.
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 4 corresponding to small filter feeding herbivorous and mixed feeding omnivorous (mostly broadcasters).
Y.-Q. Chen (1986) during the Krill Expedition from 23°N to 3°S in the Pacific East tropical (May-June 1974), this species shows a mean percentage of the total copepods: 3.0 % (day: 4.7, night: 1.3). This species was found mainly at station 10 (see chart , Fig.1) which was dominated by hydrographic conditions (see Figs. 12, 13) indicative of the California Current. The maximum number of females reached 11,900 individuals/1000 m3 in day samples and 119,000 individuals/1000 m3 in night samples. It also was found at station 22 (about 4°S), where it was concentrated mainly above 200 m in day samples. Elsewhere N. minor occurred mainly above 100 m. Its overall depth distribution tended to coincide with the depth of the thermocline. (see in Subeucalanus subtenuis Chart Fig.1, hydographic conditions Figs.12, 13).

After Samba Diouf (1991) this species is founded during May to June in the Senegal waters (T°: 22 to 29°C, Salinity between 35.8 to 36 p.1000).
