epipelagic (10-25 m). Closely related to Calocalanus neptunus but differs from it by the structure P5 (in C. neptunus they are more powerful and end by 2 long spines whereas in C. vivesi by 1 small spine). This species is dedicated by Shmeleva to Francisco Vives Galmès, who died in Majorca on 2 March 2015 {See Orbituary, Scientia Marina, 2015, 79 (2): 275-278].
