Orca Spyhopping, A website dedicated to bringing you animal facts, information and quality pictures of various species of whales, dolphins and other animals. Whales and Dolphins are Cetaceans – a group of mammals which belong to the order Cetacea. There are two classifications of Cetacea – Odontoceti (toothed Whales) and Mysticeti (baleen whales).
Whales are large, aquatic mammals that breathe air through either one or two blowholes into their lungs. Toothed whales such as Killer Whales, Sperm Whales, and Beluga Whales prey on fish, squid, or marine mammals using echolocation. Baleen whales such as Humpback Whales, Gray Whales, and Minke Whales feed on tiny crustaceans, small fish and plankton. They use their baleen to filter the food from the water and are generally larger than toothed whales.
Belonging to the odontoceti or toothed whale cetacea, and family Delphinidae, the largest family of the cetacean order, there are 26 living species of dolphins. Most species of dolphins feed mainly on small schooling fish and squid although some species prey on crabs, shrimps, and lobsters. Dolphins can be found in all oceans and major seas around the world. Each species of dolphin has adapted to life in their particular marine environment, allowing them to specialize in catching and eating food specific to that area.
