Mammals

The Mammals provides activities to explore exactly what it is about mammals that has made them so successful. Look for skeletal similarities as you try the Mammal Maker or explore the specialized diets of mammals in Beast Feast, two of the Interactive Challenges on the site.
Which mammals use tools? Which have adapted to eating water-living animals? Which adaptations have resulted in mammals without teeth? Mammals, Up-close explores the attributes of ten animals, showing similarities not evident at first glance. You can explore by species, behavior, diet, habitat, or interesting feature; you can also watch video (transcripts provided) and view images illustrating similarities across species.
