生物学     用語集 (例 epibenthic)

Found frequently in coastal waters to 10 m depth, mainly in shallow estuaries. Capable of traveling long distances, occasionally leaps out of the water. Swims in midwater. Cruises slowly over the bottom, rooting out bivalves with its beak and wings when feeding (Ref. 7251). Ovoviviparous (Ref. 50449).

Life cycle and mating behavior 成熟 | 繁殖 | 放精 | | 生産力 | 幼生

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).
