Biology 259

COMPARATIVE VERTEBRATE ANATOMY

Next offered: Fall 2010

The vertebrates are a group with a 550 million year history, represented on earth today by some 60,000 species. Vertebrates walk, swim, fly, and inhabit almost every type of habitat on the planet. They feed on everything --plants, microorganisms, invertebrates, and each other. Vertebrates range in size from a fish 7 mm long, to a whale 35 m long. Vertebrates include fishes, frogs, cats, turtles, snakes, birds, crocodiles --and us. This course examines the anatomy of vertebrates: where it came from, and how it allows them to do what they do.
