After Björnberg (1963, p.58) this species was described from waters taken off the mouth of the Amazon River by F. Dahl (1894) with surface salinity 11.8, 35.9 and 36.4 p.1000); off the Brazilian coast it is among the characteristic copepods of shelf waters with salinities 35.00 to 36.00 p.1000.
Observed in ballast waters from ships in San Francisco.
El-Sherbiny & Al-Aidaroos (2017) underline that both exogenous light signals and endogenous rhythms could be the main factors controlling the twilight of the diel vertical migration pattern (Cohen & Forward, 2005). | | | Last update : 12/02/2021 | |
