Mammals vary in size from the 100-foot-long blue whale to the two-gram bumblebee bat, one of the world's most endangered species. Most mammals measure less than one foot (including the head and body). That makes small mammals far more common, if less well known, than large mammals like elephants, tigers, and people.
Small mammals cut across categories. Most species are rodents (such as the naked mole-rat), insectivores, and bats, but there are also carnivores (such as slender-tailed meerkats), and primates (such as golden lion tamarins and lemurs).

Naked mole-what? Despite the fact that they burrow underground like moles, and have big front teeth like rats have, naked mole-rats are more closely related to porcupines and guinea pigs than to moles or rats. This naked mole-rat colony occupies a labyrinth of transparent tubes that mimics the underground tunnels and burrows in Africa, where mole-rats live. The web cam is focused on a busy intersection of two tunnels. Mole-rats are the only known mammals to live in large colonies presided over by a queen (like ants and termites).
Family members of this species greet with what looks like a kiss. They're not really kissing, but gently touching their front teeth together. What animals recognize each other this way?
For more than 30 years, this program has been saving these small monkeys through conservation breeding and reintroduction to their natural habitat in Brazil. Thanks to the success of the program, the status of GLTs was downgraded from "critically endangered" to "endangered" by the World Conservation Union (IUCN) in 2003. more
