They breathe through nostrils, called a blowhole, located right on top of their heads. By Ana Diaz Maqueda, Biologist specialized in ethology. Exciting killing missions; Awesome Visuals and sound Effects ; Smooth game play and easy controls; Lots of people to kill including Scuba Divers, Swimmers, Beach Goers, Fishermen, etc. Because whales live in the ocean, many people think they are fish. The octopus, shark, whale, starfish are all aquatic animals. Exciting killing missions; Awesome Visuals and sound Effects ; Smooth game play and easy controls; Lots of people to kill including Scuba Divers, Swimmers, Beach Goers, Fishermen, etc. The hole on top can be closed voluntarily so that the whale doesn't inhale water.

Whales, dolphins, porpoises, manatee and dugong are completely aquatic; seals, sea lions, walrus, hippopotamus, platypus, otters, … The regular production and consumption of aquatic animals have led to many endangered species. Animals like dolphin and whales breath through nostrils also called blowholes which are located at the upper part of their head. This allows them to take breaths by exposing just the top of … Animated Aquatic animals including Shark, Orca, Whale, Dolphin, Jellyfish and more. Fishes breathe air dissolved in water through special organs called gills. This has been determined by doing EEG studies on dolphins. Even though all modern cetaceans are obligate aquatic mammals, early cetaceans were amphibious, and their ancestors were terrestrial artiodactyls, similar to small deer. And they use those high frequency sounds in two different ways, to communicate, but also to "see" what's around them, without using their eyes!
