The echidna, or spiny anteater, is a marvel of defensive self-preservation, from its impenetrable spikes to its amazing ability to breathe through bushfires.
They live all around the world -- and underground. They are crazy monster diggers, strange burrowers of all shapes and sizes, who have been crawling, puncturing, and biting their way through the earth for millions of years. Join us as we travel the globe, from the dry savanna to the scrubby Australian outback to the swamps of Central America as we explore a collection of crazy diggers, including the most powerful digger on the face of the planet.
