Are beluga whales baleen or toothed?
Beluga whales are odontocetes, or toothed whales. Living mainly in Arctic waters, baby belugas are born gray; only later do they become white. Toothed whales such as sperm whales hunt their prey one by one. They often use echolocation to find it and sometimes swallow it whole.
Are baleen whale toothed whales?
There are two types of whale; baleen and toothed. The key difference between them is the way they feed and what they have inside their mouth.

Do baleen whales use echolocation?
Toothed whales and dolphins (for example killer whales and bottle-nose dolphins) use echolocation for hunting and navigating, while baleen whales (for example humpbacks and blue whales) generally produce a series of sounds which are frequently termed ‘songs’ that are used for communicating.
What do toothed whales eat?
The majority of toothed whales will eat whale food species such as squid, octopus, crustaceans and fish. Other toothed whales, such as the killer whale, will hunt bigger marine mammals including whale food such as seals, sharks, birds, and even other whales.
