I also did a little project about Rainforests, specifically Tropical ones. Even though they only cover 2% of the Earth, they're home to over 50% of the Earth's plants and animals! Wow! There's a really cool type of plant called a Bromeliad. They have long leaves that curl at the bottom to collect raindrops and let them run to the middle of the plant. The middle of the plant is like a water tank and traps all the water there. The biggest type of Bromeliad can hold up to 2 gallons of water!

Bromeliads are special for another reason; the Poison-Arrow Frog doesn't lay its eggs in the water, it lays them on the ground! Then the male frog comes along and fertilizes the eggs and guards them untill they turn into tadpoles. Then the tiny tadpoles wriggle on to their mother's back ahd she carries them to a water-filled Bromeliad that she has chosen for her tadpoles' home. The journey can take a few days, especially if she has to climb high into the Canopy layer of the rainforest. When the frog reaches the Bromeliad, she drops each of her tadpoles into a seperate tiny pool of water. The tadpoles feed on the algae in the water, but to be sure they get enough food, their mother returns again and again and deposits a single unfertilized egg in the water for each tadpole. Mmm, a tasty snack!
After 6-8 weeks the tadpoles emerge as frogs and return to the forest floor. Amazing!
