Which parent is responsible for mouthbrooding the developing eggs and fry in Arowanas?
Answer
The male Arowana
Reproduction in Arowanas involves a strong commitment to parental care demonstrated through mouthbrooding. In this system, the male Arowana assumes the primary responsibility for guarding the offspring. After fertilization occurs, the male holds the developing eggs within his mouth until they successfully hatch. This sheltering behavior frequently continues for a period after hatching, protecting the vulnerable fry from predation in their challenging natural habitats.
