Known for their silvery sheen, dolphins have a bottle-shaped nose.

Popular worldwide for appearances in movies and aquariums, dolphins reside in warm waters in pods. Pods range in size from fifteen to one hundred dolphins or even one thousand animals! On average, these mammals are eight feet long, weighing five hundred pounds. Dolphins have shrimp, eels, squid, or other fish on the menu for dinner. To help with finding food, dolphins use echolocation. They also make noise to communicate with other dolphins. With each other, these fish are very affectionate. Dolphins also have a good relationship with humans. Because of its intelligence, the United States Navy trains dolphins to detect mines and other dangers underwater.
