(Intro)

It's a drizzly, rainy day outside, so we thought we'd pull out a few of our books and explore some cool colorful places where wet weather is pretty much the only weather there is.  I'm talking about rainforests.  You can probably tell from the name that rainforests have a whole lot of two things: trees and rain, and sure enough, rainforests get more rain than any other place on Earth.  In some areas of the rainforest, it rains every day and people often think that rainforests all look like this: warm and steamy with animals like colorful birds and plants like bananas and mango trees, and there are lots of rainforests like that, but a rainforest can also look like this.  

Home to animals that are adapted to cooler weather, like bears and elk.  Both of these places are rainforests, but they're found in different parts of the world.  The warm rainforests are found here, close to the imaginary line that runs around the middle of the world.  This part of the world is called the tropics.  It gets lots of sun, which is why the temperature is really warm almost all of the time, and there are a lot of different kinds of plants and animals that live in these warm rainforests.  

So many, in fact, that scientists talk about the rainforest as having layers that change as you go from the top to the bottom and different animals and plants live in each layer.  For example, at the top layers of the rainforest in the tropics, all you can see is the very tippy tops of the tallest trees.  There's lots of sunlight up there that the trees use to grow so these tall trees have lots of leaves, and these big leafy trees make lots of shade.  They block some of the sunlight from getting to the lower layers, kind of like a big green umbrella, and all of the leaves and fruit in the top layers means that there's plenty of food for animals to eat.  So many different kinds of animals live up here, like insects, parrots, bats, monkeys, and sloths.  Some of these animals never even go down to the ground at all.  They don't need to!  Everything they need is at the top of the rainforest.  

Now, the lower layers don't get as much sunlight as the top, but they're still home to plenty of living things, like snakes, lizards, and even big cats like tigers and jaguars and just like the animals at the top of the rainforest, animals down below are perfectly suited to the place where they live.  The big cats, for example, have patterns on their coats that help them blend in with the rainforest.  The jaguar has spots and the tiger as you all know has stripes and these patterns help the animals hide amongst the shadows of the trees.  

Okay, but what about the cooler rainforests?  They're found here, much farther away from the tropics.  These rainforests are cooler because they don't get as much sun as the warmer ones.  They also have layers, but the plants and animals that live there are pretty different.  The top layer of cooler rainforests, for example, is made of conifers.  Those are the kinds of trees that usually have cones, like pines and redwood trees, and these kinds of trees have needles too, like some other kinds of evergreens.  These needles help the trees save energy during the cold winters and it's not only the plants that are different here.  

Animals that live in these rainforests also have to be able to live in cooler temperatures, so many of the creatures that live in the lower layers of these rainforests have coats that help keep them warm.  For example, some tigers live in these cool rainforests and they also have striped coats that help them blend into the shadows, but their fur is nice and thick, so it keeps them warm, and other furry mammals live in these cold forests, like brown bears, black bears, and elk, quite different from the macaws and monkeys that live in the warmer forests.

Wow, that was quite an imaginary tour.  We went all over the world in just a few minutes.  But now, I want to find out even more about the amazing rainforests around our world.  Come on, Squeaks, let's head to the library.
