Fun Fact: Glossodoris sp.01 (NSSI2) is part of a group of still-undescribed species. Its distinctive body patterns and colours help scientists identify it, even though it’s not formally named yet—making every sighting feel like a discovery.

Elegant, smooth, and beautifully patterned, Glossodoris sp.01 (NSSI2) is a delight for macro enthusiasts. Its gentle movements and vivid mantle details make it an excellent subject for close-up photography on any tropical reef dive.
