Naked mole-rats always flash their pearly whites. That's because their lips close behind their ever-growing incisors. This enables them to dig without getting a mouthful of dirt! Strong jaw muscles help them power through hard-packed soil with ease.
In celebration of #GivingTuesday, donations made in support of our new naked-mole rat habitat by midnight will be matched up to a total of $1,000 by a generous donor. Give today, Nov. 28, to make your contribution go farther: https://nationalzoo.si.edu/dreamhome. (Link in our profile.)
