			What are cetaceans?
		What are cetaceans?
Whales, dolphins and porpoises are collectively called cetaceans, since they all belong to the order Cetacea. [Learn more]

		What is the difference between toothed and baleen whales?
The order Cetacea is divided into 2 suborders: Odontoceti and Mysticeti.
Dolphins and porpoises, along with other species such as the sperm whale, the beaked whales, the narwhal and the beluga are Odontocetes - i.e. they have teeth.
On the contrary, proper whales (mysticetes) do not have teeth. Instead, they have a large number of comb-like keratin plates, called baleen, hanging from the upper jaw. Baleen plates act like a sieve, allowing whales to filter the plankton and small fish they feed upon.

			Are cetaceans mammals or fish?
		Are cetaceans mammals or fish?
Cetaceans (whales, dolphins and porpoises) are mammals. They are warm-blooded and give birth to live offspring, which are breastfed. Unlike fish, cetaceans are unable to extract oxygen from the water and therefore need to periodically surface in order to breathe.

			How does a cetacean breathe?
		How does a cetacean breathe?
Cetaceans breathe air at the surface of the water through their blowholes, the equivalent of our nostrils. Mysticetes (baleen whales) have two blowholes while odontocetes (toothed cetaceans) have only one blowhole.
Unlike humans and most other mammals, they are unable to breathe through their mouth, which makes it possible for them to feed underwater while keeping their respiratory system free of water.

			How do whales and dolphins swim?
		How do whales and dolphins swim?
Cetaceans use their tail to swim. Unlike fish, the tail of whales, dolphins and porpoises lies in an horizontal plane and it is moved up and down rather than from side to side. Muscles actively work when the tail is raised, while they rest (or almost completely rest) when the tail is lowered.
