Whales

Whales are fully aquatic mammals that breathe air through blowholes on top of the head. Baleen whales filter food from water, while toothed whales capture individual prey. Their bodies are streamlined for swimming, with horizontal tail flukes providing much of the driving force. Mothers give birth to live calves and feed them rich milk. Sound is important for communication, and toothed whales also use echolocation to locate objects and prey. Species range from coastal residents to ocean travelers that move seasonally between feeding and breeding areas.
