The mean female size is 1.587 mm (n = 8; SD = 0.2948) and the mean male size is 1.243 mm (n = 4; SD = 0.1658). The size ratio (male : female) is about 0.82 | | | | Rem.: | epipelagic. For Frost & Fleminger (1968, p.38) C. lividus female is distinguished from the very similar ingens by the shape and curvature of the forehead and rostrum in lateral view. C. lividus and laticeps differ in the inclination of the rostrum in lateral view, the length-width ratio of the caudal ramus, the form and spacing of basipodite 2 spiniform processes 2 and 3 of P3, and usually in the shape of the frontal region of the anterior portion of body including the cephalosome and fusedthoracic segment bearing P1, in lateral and dorsal view. C. lividus female differs from jobei and minor in the form of the rostrum in lateral view. The male of C. lividus is distinguished from ingens by the Prosome/Urosomal segment 2 length ratio and the length-width ratio of the left 2nd segment of P5. C. lividus and males differ in the urosomal segment 2/2nd segment of P5 and urosomal segment 3/3rd segment of P5 length ratios, in the length-width ratio of the caudal ramus, and in the form of basipodite 2 spiniform processes 2 and 3 of P3. The name lividus refers to the blue or lavender tint observed in the cuticle of late copepodid and adult specimens.
See in the annex (in Razouls, 1972, p.30-32) the comparison with the females of this species and Clausocalnus mastigophorus, notably the variability of the rostrum (figs31 and 33).
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). | | | Last update : 04/12/2020 | |
