About Us

Reef Life Survey is a non-profit citizen science program in which trained volunteer SCUBA divers undertake detailed surveys of reef biodiversity on rocky and coral reefs around the world.


With a dedicated team of more than 70 volunteer divers,
armed with an extensive knowledge of reef species & a single standardised set of scientifically-robust methods, RLS records the abundance, size and location of conspicuous reef-dwelling species on reefs around the world.


RLS represents a unique collaboration between professional and citizen scientists, with a joint mission to provide high quality, unbiased & publicly available ecological information that is used to better inform management & policy, and to build a great public understanding on the status of the world’s reefs.


Our rapidly expanding database of abundance and occurrence records and high quality species photos inspired the creation of the RLS Reef Species of the World online field guide – the most comprehensive of it’s kind in the world.

Our online field guide was designed by underwater naturalists for underwater naturalists, and features detailed profiles for more than 4, 500 reef species from 53 countries.
