The smooth lanternshark feeds on squid, lanternfishes, smaller dogfish sharks, and fish eggs, as well as crustaceans and fish.
 This species is ovoviviparous, with the developing embryos being sustained by a yolk sac.
Females produce an average of 10 young per reproductive cycle.
Males reach sexual maturity at a length of 31–39 cm (12–15 in), and females at a length of 38–47 cm (15–19 in).
The length at maturity varies with geographical region, with sharks in the western Atlantic maturing larger than those from off KwaZulu-Natal.
This species grows at a slow rate, with the body becoming relatively longer with age.
Off southern Portugal, males live to at least 13 years of age, and females to at least 17 years.
