Lesson by Kerry M. Kriger, animation by Simon Ampel.

Disappearing Frogs, is a TED-Ed Animation by Dr. Kerry Kriger, Founder of SAVE THE FROGS.

About the Animation

Frogs (and amphibians in general) are in danger—worldwide, nearly one-third of the world’s amphibian species are on the verge of extinction. And yet, frogs contribute to our well-being in many important ways. In this educational animation, Dr. Kerry M. Kriger describes why frogs are in trouble and how you can help save them.

Additional Resources

The best way to save the frogs is to educate yourself about amphibians and amphibian conservation, and fortunately, there are many free educational resources online. A great place to start is www.savethefrogs.com, which has several hundred pages of free information on frogs. The website was created by Dr. Kerry Kriger, who founded SAVE THE FROGS! nonprofit organization and wrote the script for this video.

The SAVE THE FROGS! How To Help page offers over 50 ideas on ways to help frog populations. SAVE THE FROGS! Academy offers free online classes twice weekly, open to all people interested in frog conservation; videos of all the SAVE THE FROGS! Academy classes get archived here.

AmphibiaWeb is a fantastic website that provides a database of all the world’s amphibians, so if you want to know what lives in your part of the world, that is a great place to start.

What’s one thing that every living creature on earth needs? Water. We know that frogs require a wet environment in order to survive. However, there’s a species of frog that inhabits areas with only a few months of rainfall each year? Meet the Litoria platycephala—a frog species with some pretty cool ways in which they overcome the limitations of the harsh Australian environment. The gastric brooding frog lays its eggs just like any other frog—then swallows them whole to incubate. That is, it did until it went extinct 30 years ago.

The Mindo Glassfrog, seen just twice in the wild since it was first described in 1975, has become the highlight of a new scientific paper identifying the Río Manduriacu Reserve as a key breeding site for the species. The Revelator, an online news and ideas initiative of the Center for Biological Diversity, published a great article on the discovery and the threats facing their habitat.
