Life starts right as the central yolk splits in two. These legs start out as bulges in the front and back of the tadpole. Toad tadpoles take a little bit longer, becoming toadlets after about two months. Most species of frogs will lay their eggs in water usually in spring (some species lay eggs on land). So, to live, some tadpoles release toxic chemicals to kill the tadpoles in the unhatched eggs. When the rain comes along, after developement of 7 to 9 days, the foam drips down, dropping tiny tadpoles into the river or pond below. Out of those, only a few go on to live. An egg that has not been fertilized will not begin the process of cell division that results in a tadpole. Also, the adult completely absorbs the gills. They’ll feed on algae and other little plants. Soon, it will leave the water, only to return again to laymore eggs and start the process all over again! By now the diet may grow to include larger items like dead insects and even plants. The female frog will lay many eggs in a large clump called a clutch that is surrounded by a jellylike substance which may be attached to vegetation in the pond or may be free floating in the center of the pond. Also purchased mine at Dollar Tree. A toad will lay strands or lines of eggs. As the adults grow, they shed their skin and eat it. Frogs are amphibians: cold blooded animals that are vertebrate, meaning they have a spine and have two phases in development. Rainwater is as good as it gets. Frogs tend to lay many eggs. Stage 2: Tadpole. A floating clump of eggs is called frog spawn. Amplexus usually occurs in the water, but some frogs like to mate on land or in trees.
