Dolphin Portal

Dolphins are active predators and eat a wide variety of fishes, squids, and crustaceans such as shrimps. The foods available to a dolphin vary with its geographic location.
Coastal dolphins tend to eat fishes and bottom-dwelling invertebrates.
 

Offshore dolphins tend to eat Some offshore dolphins were found with deep-sea fishes in their stomachs. This evidence suggests that offshore dolphins may dive to more than 500 m (1,600 ft.).

On average an adult dolphin will eat 4-9% of its body weight in fish, so a 250 kg (550 lb) dolphin will eat 10-22.5 kg (22-50 lb) fish per day.
