| Descrição do ciclo de vida e do comportamento reprodutor | Males and females appear externally alike (Refs. 2279 & 9245). In 'Serrasalmus sp. aff. nattereri', reported to occur in the Orinoco basin (Venezuela, Guyana), the males have more 'bull-like' heads, but are more slender than females (Ref. 1672). Eggs are laid on tree roots trailing in the water and are guarded; the reproductive success may vary strongly from year to year depending on how the savanna was flooded (Ref. 9078). The eggs are large, adhere to plants and are not attacked by the parents. They hatch in 9 to10 days (Ref. 7020). |
