The adults prefer to swim in the open ocean where they have more room.

Explanation: Estuaries act as nurseries—they provide abundant food and shelter for juveniles. As organisms mature they typically move out to the open ocean (or other adult habitats) for feeding, breeding, and larger ranges; estuarine conditions and space are better suited to young life stages than most adults.
