It is parasitised by the monogeneans Pseudoleptobothrium christisoni on the dorsal skin surface (Ref. 124055) and Neoheterocotyle robii on the gill lamellae (Ref. 124054).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). 2-10 young born in the summer (Ref. 5578).
