E. Saiz et A. Calbet, On the free-spawning reproductive behaviour of the copepod Clausocalanus lividus (Frost & Fleminger 1968), J PLANK RES, 21(3), 1999, pp. 599-602
Unlike other species of Clausocalanus, which are egg carriers, Clausocalanu
s lividus lays free eggs into the water. As far as we know, this is the fir
st observation of such a difference in reproductive strategy within a genus
of calanoid copepods.
