Oviparous, paired eggs are laid. Embryos feed solely on yolk [733]. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother [17086]. Reproductive biology: Portuguese continental waters (data base: 856 specimens, 501 females, 355 males): No difference in size at maturity was detected between sexes, which was estimated as 56 cm total length. Spawning occurs all year round, but maximum activity was during winter months. Maximum fecundity is c. 63 eggs female−1 year−1. Encapsulated eggs are released in batches, nine in total with a mean number of seven extruded eggs in each batch [17307];
