- Aspects of the biology of the leaf‐scale gulper shark Centrophorus squamosus (Bonnaterre, 1788) off Madeira archipelagoPublication . Severino, Ricardo B.; Afonso-Dias, Isabel; Delgado, João; Afonso-Dias, ManuelA total of 206 Centrophorus squamosus (Bonnaterre, 1788) with a total length ranging from 89 to 146 cm were captured at an average depth of 1200 metres. Of the 61 females sampled, 34% were gravid, showing an absolute individual fecundity of two to ten embryos (pups). The results clearly indicated that this deepwater shark spawns in the Portuguese waters off Madeira archipelago.
