Coming to you "Live from the Field" for 2 weeks! My blog is designed to share this incredible experience with my students, colleagues, friends, and family.
Unique features: 1. Mammary glands (they produce milk) 2. Sweat glands 3. Covering of hair (replaced by scales on armadillos and whiskers on whales) 4. Claws, nails, hooves, and/or antlers 5. Jaws that move side-to-side 6. Ear structure that includes an inner and outer ear (amplifies sound) 7. Can breathe (lungs) and chew at the same time 8. Reproductive systems (eggs or pouches) Important features: 1. Warm-blooded (birds are too!) 2. Highly developed brain 3. Specialized teeth (due to jaw)
