জীববিজ্ঞান     শব্দকোষ (উদাহরণ স্বরূপ epibenthic)

Inhabits coastal waters (Ref. 7251). Generally found near shore, to depths of 10 m. Both adults and juveniles frequent estuaries and surf zones (Ref. 27549). Bottom feeder with fish, clams, worms and shrimps. It causes a number of injuries to bathers and waders (Ref. 26938). Ovoviviparous (Ref. 50449). Litters of 2-4 pups; gestation 10-11 months, including a period of embryonic diapause (Ref. 114953).

Life cycle and mating behavior Maturities | প্রজনন | Spawnings | Egg(s) | Fecundities | শুককীট

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). Distinct pairing with embrace (Ref. 205).
