Echolocation allows dolphins to locate food and other objects in darkness or in murky waters, where sight is nearly useless. Though bottlenose dolphins are fast, powerful swimmers, capable of tremendous leaps out of the water, they often take a free ride by surfing in the bow of fast-moving vessels. Seals The Aquarium has harbor seals and gray seals. There are several visible differences between seals and sea lions. Seals cannot stand on their flippers as sea lions can.
Seals move on land by wriggling their bodies.
In the water seals use their rear flippers for swimming and their front flippers to steer. Sea lions do just the opposite. Seals do not have ear flaps and sea lions do. Both seals and sea lions are carnivorous and feed primarily on fish. On the fifth level of the Aquarium an exhibit simulates an Amazon rain forest of South America.
