PLANET EARTH Jungles
She's heading towards the loudest call, because loud calls come from big frogs and big is best, but to reach him she must run the gauntlet of a gang of smaller suitors. Their only chance of mating is to make a sneaky interception（偷偷摸摸的拦截）. He's scored（刮伤的）. But with more females arriving all the time, it's not over until the fat frog stops singing. Feet, so vital for gliding, are now put to other uses.
Two's company, three's inconvenient but in any case, all male frogs are equipped with dry thumbs which enable them to get a vice like grip on their moist partners. It's a case of first come first served. Living in such a humid environment, means jungle frogs are less tied to puddles and pools and these even lay their eggs out of water. There's little chance of them drying out and up here they're safer from predators.
Surprisingly, it doesn't rain every day in the rainforest but more still falls here than anywhere else on Earth. On average, over two meters a year. A single tree can suck up hundreds of tons of water each year but the trees can't use all this water, so, much of it returns to the air as vapor, forming mist and clouds.
