| Descrição do ciclo de vida e do comportamento reprodutor | 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). Bears up to 4 young (Ref. 5578, 6871, 37816). Width at birth 17-35 cm (Ref. 37816). According to Uchida et al (1990) (Ref. 51119) 'the male chases the female in mid water, then nibbles on her dorsal surface. The female stops swimming to begin copulation. The male bites the female on a pectoral fin and bends one clasper forward, then attempts an abdomen to abdomen copulation with either clasper, usually mid-water' (Ref. 49562). Copulation lasted for 20 seconds to 1 minute (Ref. 49562). |
