About Cetaceans
Cetaceans are marine mammals with streamlined (hydrodynamic) bodies that glide easily through their watery environment, horizontal flukes, front flippers for steering and a layer of blubber directly under the skin. According to the Society for Marine Mammalogy, 90 species of whales, dolphins, and porpoises are included in the Order Cetacea.
