Red-Eyed Tree Frog Tadpoles
These tadpoles have an extreme entrance into the world. Their mother births a batch of eggs on a leaf, which hangs over a pond. When the tadpoles are ready to hatch, they swirl around until the eggs break open. Then, they fall down the leaf and into the pond below. Straight from birth, these tadpoles have adapted to their surroundings to survive any sort of predators. They have sucker-like mouths that allow them to cling to the undersides of leaves above the water, to help them avoid predators (National Geographic).
