Animal Misfits

The Season 33 premiere spotlights such quirky creatures as the giant panda, which eats 16 hours a day; and the big-headed mole rat of Ethiopia's Bale Mountains, which unlike other mole rats heads above ground to eat. Also: an ant-sized chameleon; the mudskipper fish, which can live out of water; the deep-sea nautilus; New Zealand's kakapo, a flightless parrot; and the Arctic woolly bear caterpillar, which spends most of its life frozen.
