Snorkeling over the reef and wondering who just swam past? With Riffblick you get to know the animals before your trip, in five minutes a day.
How you learn
First you get to know the big groups on the reef and recognise them in photos: parrotfishes, surgeonfishes, groupers and many more. Then come the species you'll meet on almost every snorkel. You see a photo and pick the name, or the other way round. It gets more detailed step by step, all the way to look-alikes and rare species. In every lesson you see the new animals as cards first and are then quizzed, with animals from earlier lessons mixed in to make them stick. Whatever you got wrong comes back until it sticks. Riffblick schedules reviews with the FSRS method, like good flashcard apps.
Five dive regions
Red Sea · Indian Ocean with the Maldives and Seychelles · Great Barrier Reef and Coral Triangle · Caribbean · Galápagos and Eastern Pacific. Each region has its own learning path with the species that really live there.
More than fish
Sharks, rays, dolphins, dugongs, sea turtles, corals, sea stars, clams, nudibranchs and octopuses. Over 300 species, with photos of real animals underwater.
What makes Riffblick different
• Look-alikes: two similar species side by side, with what tells them apart.
• Careful, venomous: you learn fire coral, stonefish and lionfish early on.
• Night dive: a moon marks the animals that are out at night, and every region has its own night chapter.
• Reef health: indicator species tell you how healthy a reef is. For many species you can read what lots or few of them say about overfishing, collecting or algae.
• Facts with sources: size, diet and habitat come from FishBase, SeaLifeBase and the scientific literature. The sources are listed for every species.
• Names in English or scientific, whichever you want to learn.
Your logbook
Log what you've seen with place, date, note and your own photo. Your sightings appear on the map and become a chapter of their own. Animals you still want to see, you learn ahead of your trip.
Keep going with Okta
