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 http: //www. flickr. com/photos/twinsis/2500638119/ http: //www. flickr. com/photos/mrmritter/2684355198/

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 http: //www. flickr. com/photos/masseea/4541027130/ http: //www. flickr. com/photos/9052612@N 08/672510822/

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 • •
