Whales Order Cetacea: (from the Latin word cetus meaning sea monster)

Whales are Mammals Live birth Warm-blooded Breathe air Have hair (very little, why?)

Two suborders of whales Toothed Whales (Odontoceti) – Dolphins, porpoises, killer whales, pilot whales, sperm whales Baleen Whales (Mysticeti) – Right, Blue, Gray, Fin, Humpback, and Minke Whales

Baleen Whales Feed in Two Different Ways Humpback whales gulp and strain – Gray whales excavate by gulping and straining sediment Right Whales skim, filter and lick

Adaptations of Whales Streamlined bodies Reduced hair Tail adapted as fluke Fused bones in the front “hands” make great flippers for swimming Layer of blubber for insulation and energy reservoir

How are whales different from sharks?
