The frog is probably the most widely-known and recognized amphibian in the whole of the animal kingdom, and their fascinating life cycle development can serve as a template for understanding amphibians more generally. They begin life as one cell creatures, after which they progress through six tadpole stages, growing a tailbud, external gill, internal gill, hindlimb, forelimb, and shortened tail, in that order. Afterwards, the fully developed tadpole matures into a froglet.
With this educational specimen, you can see firsthand all of the stages of a life of a common frog. The block features real-life samples of the one cell stage, all tadpole stages, and a small froglet. All of this is nicely presented in an acrylic block. Used as a slide under a microscope or as a hands-on specimen, this makes a fantastic addition to any science classroom.
