Franciscana Dolphin: Pontoporiidae

Diet

Franciscana dolphins eat a wide variety of small bottom-dwelling fish, squid, octopus, and shrimp. Most of the fish they feed on are less than 4 inches (10 centimeters) long.

HOW DO DOLPHINS SLEEP?

Dolphins must rise to the surface to breathe every few minutes. How can they do this and still sleep? The answer is found in the way their brain functions. One half or hemisphere of the brain rests, while the other stays alert and makes sure the dolphin surfaces and breathes. When one half of the brain is rested, it takes over and the other half sleeps.
