Bite-sized pieces: Redmap Report Card 2016

Australians have shared more than 2100 photos on Redmap of unusual or rare marine life in their local seas. Top-sighted Redmap species include threadfin butterflyfish in NSW, eastern rock lobster in Tasmania and redthroat emperor in WA. More than half of the sightings were submitted by divers. And the community data was used or mentioned in 23 scientific papers! The Redmap Report Card recaps who spotted what where around the country.

Redmap's top verifying scientists

Redmap has a secret weapon: a network of 80+ marine science boffins around Australia. These experts verify sighting photos so they can be added to the Redmap database and displayed on redmap.org.au. Meet 5 Redmap scientists who've reviewed the most sightings on Redmap - and some of the marine life they've verified.

Redmap animation: sightings over time!

Fishers and divers around Australia have been sharing their knowledge with Redmap since December 2009. This animation by Cecilia Villanueva shows all the amazing out-of-range and unusual observations submitted over that time! 'Listed' species are the ones Redmap highlights as species of interest on the website and 'other' species are ones you have recognised as out of place or rare. Dots often represent multiple sightings in one spot!
