Frog Lifecycle Puzzle with Image Tray
THE BELOW INFORMATION IS PRINTED ON THE BACK OF THE TRAY:
Frogs belong to a group of animals called “Amphibians”. Amphibian means two-lives. Frogs lay their eggs in water or wet places. A floating clump of eggs is called frog spawn. The single cell in the egg eventually splits into two. These two split making four cells, and so on. Eventually, there are many cells in the egg. The mass of cells in the egg come to form an embryo. Organs and gills begin to form, and in the meantime, the embryo lives off of its internal yolk. This supplies it with nutrients for 21 days. After its 21 day development period, the embryo leaves its jelly shell, and attaches itself to a weed in the water. This quickly becomes a tadpole, a baby frog. The tadpoles grow until they are big enough to break free into the water. This can take from 3 days to 3 weeks, depending on what kind of frog they will become. They eat very small plants that stick to larger plants in the water. These tiny plants are called algae. The tadpole is extremely vulnerable, and must rely on its camouflage to protect it. After about five weeks, the tadpole begins to change. It starts to grow hind legs, which are soon followed with forelegs. Behind their heads bulges appear where their front legs are growing. Their tails become smaller. Lungs begin to develop, preparing the frog for its life on land. Now and then, they wiggle to the surface to breathe in air. The tail becomes larger and makes it now possible for the tadpole to swim around and catch food. They eat plants and decaying animal matter. Some tadpoles eat frogs eggs and other tadpoles. Over time, the tadpole becomes even more froglike. They have shed their skin and lips. Its mouth widens, and it loses its horny jaws. The tail becomes much smaller, and the legs grow. The lungs are almost functioning at this point. Eleven weeks after the egg was laid, a fully developed frog with lungs, legs, and no tail emerges from the water. This frog will live mostly on land, with occasional swims. Small to medium sized frogs eat insects such as flies, mosquitoes, moths and dragonflies. Larger frogs will eat larger insects like grasshoppers and worms.
