We have our fifth round of weekly additions—Bottlenose Dolphin. Bottlenose Dolphins are fully aquatic oceanic mammals and are closely related to porpoises and whales. These animals are highly intelligent and have even been trained to locate sea mines and divers. Bottlenoses use a form of sonar called echolocation to stalk their prey which consists mainly of small fish crustaceans and squid. These animals are cosmopolitan across the worlds oceans.
