Vertical distribution of Scolecithrix bradyi in the Florida Current (SL 53 station, B 1-9).
Nota: This distribution suggests an upward migration at night.
Species Scolecithrix bradyi - Distribution map 5issued from : A.A. Shmeleva in Bull. Inst. Oceanogr., Monaco, 1965, 65 (n°1351). [Table 6: 21 ]. Scolecithrix bradyi (from South Adriatic).
Dimensions, volume and Weight wet. Means for 50-60 specimens. Volume and weight calculated by geometrical method. Assumed that the specific gravity of the Copepod body is equal to 1, then the volume will correspond to the weight.

Rem.: epipelagic. (off Malta: depth sample: 1500 m). Sargasso Sea: 0-500 m (Deevey & Brooks, 1977, Station "S"). 82-301 m at Station N-1 (SW Bösö, E middle Japan) from Furuhashi (1966 a ).
The species resembles S. danae, but differs in having longer extensions on the posterior last thoracic segment, a female P5 and a bifurcate terminal segment on the male right P5..
Recorded from the warm waters in Japan. Rare in the Izu region.
After Lapernat & Razouls (2002, p.19) the Itoh's index value of the mandibular gnathobase = 703.7 (number of teeth: 10) on the right Md, and 1473.2 on the left Md; for Gaudy & Boucher (1983): 570.
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 omnivorous.
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 5 corresponding to small sac-spawning detritivorous.
