“Tadpoles: The Big Little Migration”

Amphibians like toads are often indicator species for their ecosystem because they are vulnerable to changes on both land and water. In this short film, videographer Maxwel Hohn follows the migration of western toad tadpoles in British Columbia, showing their daily underwater journey from deep waters, where they can hide, to warmer, shallow waters, where they eat. Over the days and weeks of their early life, millions of tadpoles make the journey, their bodies morphing as they do. Eventually, they will hop away as toadlets. (Video and image credit: M.
