Spinner dolphins also help each other out . For example, if a dolphin gets sick and can't come up to the water to get air , the dolphins get underneath the sick dolphin and tries to push it up to the water so it can get air . These dolphins can only hold their breaths for up to ten minutes . Well they do sleep , but not for long periods of time like humans. The Spinner dolphin makes a whistling noise when communicating with other dolphins and when they get excited .
Dolphins eat mostly fish and squid .
The kinds of fish they eat are Marco , herring , sardines , shrimp , and crustaceans . The Spinner dolphin eats about 66 pounds of food every day . The Spinner dolphin is very good in catching its prey even when it's dark . After that sound has hit something an echo comes back to the dolphin so it could catch its food for the day .
