They feed by straining tiny shrimp-like creatures called krill through the fringed plates of long, fingernail-like material called baleen attached to their upper jaws. Whales, particularly humpbacks, produce otherworldly vocalizations that can be heard for miles underwater. The songs, complex combinations of moans, howls, and cries that can continue for hours, are produced when whales push air around in their heads, then amplify the sounds through a blob of fat that perches on the top jaw.
Though the stark population declines from hunting have largely stopped , several whale species are threatened or endangered—including the blue whale , right whale, and fin whale—by a combination of fishing net entanglements and being struck by ships.

There are 65 different species of toothed whales Odontoceti. These types of whales are classified as such because they have teeth, one blowhole, and are smaller than baleen whales. Toothed whales are also hunters and can find their prey using echolocation. Beluga whales have bright white skin that makes them easy to spot, but also helps them blend in with floating ice in the Arctic.
The whales are also sometimes known as white whales. Belugas have a sophisticated sonar system that is used to maneuver through shallow water. They are often found in the northern hemisphere close to the Arctic.
Narwhals are also found in colder waters. Their most prominent characteristic is the long tusk on their bulbous heads, their arched mouth line, and a dorsal ridge rather than a fin. There are two subsets of pilot whales, short-finned and long-finned. Short-finned pilot whales prefer warmer waters while long-finned whales prefer colder temperatures. Long-finned whales are most commonly found in the North Atlantic. These whales are leisurely swimmers. They are well-known for logging. Fishermen often see them float motionless on the surface and they appear like logs in the ocean.
Sperm whales have a single blowhole on their left side, which makes them distinctive from a distance. They are toothed whales that gather in family-oriented pods of 10 to They are popular animals for marine parks, a practice that is growing more controversial. The beluga whale was called the "sea canary" by sailors because of its distinctive vocalizations, which could sometimes be heard through the hull of a ship. Beluga whales are found in Arctic waters and in the St.
Lawrence River. The beluga's all-white coloration and rounded forehead make it distinctive from other species. A toothed whale , it finds its prey using echolocation. The population of beluga whales in Cook Inlet, Alaska, is listed as endangered, but other populations aren't listed. Bottlenose dolphins are one of the most well-known and well-studied marine mammals. Their gray coloration and "smiling" appearance make them easily recognizable.
Bottlenose dolphins are toothed whales that live in pods of up to several hundred animals. They can be found close to shore, especially in the southeastern U. Risso's dolphins are medium-sized toothed whales that grow to about 13 feet long. Adults have stout gray bodies that may have a heavily scarred appearance. The pygmy sperm whale is an odontocete, or toothed whale, with teeth only on its lower jaw, like the much larger sperm whale.
It's a fairly small whale with a squarish head and stocky appearance. The pygmy sperm whale reaches average lengths of 10 feet and weighs about pounds.
