Tiny creatures that form the basis of the food web - the world of micro invertebrates

Did you know that the eggs of some tiny little organisms can remain viable for up to 400-500 years?

Dr Robert Walsh is an aquatic micro invertebrate ecologist. In other words, he’s an expert in micro fauna, the tiny little animals that form the basis of the food web in our waterways but which are invisible to the naked eye.

In this week’s podcast he takes us on a tour of the fascinating world of micro invertebrates including a fascinating story about how they’ve been found in mud bricks in the desert and when distilled water is added they come back to life! So species that were once thought extinct 400-500 year ago, may only need a splash of water to spring back to life.
