Sea Slug Ecology and ID Course


Sea Slug Ecology and ID Course

At the top of many diver’s bucket lists are those colorful and and fascinating group of marine gastropods known commonly as Nudibranchs. Their biodiversity is an indicator of total reef diversity, and also can be used when assessing changes in the physical or biological composition of marine areas in the face of disturbances. In our course you will learn about the ecology and taxonomy of sea slugs, and about how to conduct scientific surveys to monitor their abundance and diversity.
