Dolphins spend very little time searching for their food. They can eat for about two months and not eat again for another month because they live of their blubber.
Most dolphins die from foreign object being thrown into the ocean.
Not all dolphins swim way out in the ocean. Some dolphins, such as the Commerson dolphin swim in the shallow coastal areas in the water. Calfs can be 90-130 centemeters long and will grow to about 4 meters long in 40 living years. They are used for grabbing food, but not chewing since dolphins swallow their pray. Dolphins can hold their breath for five to eight minutes.
