"Imagine saving an entire marine ecosystem by protecting an inconspicuous and 'un-cute' animal you've never even heard of," says Center for Coastal Studies marine biologist Agnes Mittermayr in a funny and illuminating conservation talk.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at
