NARRATOR: While the rivers and ponds are melting, the ground remains frozen. And under the leaf litter, someone is pulling off a miracle. [intriguing music] This wood frog is frozen solid. Even his eyes are iced over. There's no pulse, no breath. Slowly the warmth of spring begins to thaw, from the inside out. His heart starts beating. [dramatic music] His brain lights up-- [intriguing music] -- and he begins to move. It turns out that the frog's liver pumped a syrupy, natural antifreeze into his cells in the fall. It kept his organs from freezing. Only the water between cells froze. After eight months frozen, he's completely undamaged, and leaping straight for the nearest pond. [water splashing] Now, Alaska's least welcome yearly arrival slowly bursts from its watery home-- the mosquito. [intriguing music] And it immediately wants blood. Not even cold-blooded frogs are immune. The number of mosquitoes here far outstrips that in any jungle on earth. [music continues] [water splashing] [mosquitoes buzzing]
