Pick a kind of water and meet one of 349 real fish—photo, diet and adaptation.
Let the current decide across every depth · all depths · 349 fish in this pool
Reef shelf · surface–50 m
Amphiprion ocellaris
Why it lives here
A protective mucus layer lets it live among a host anemone's stinging tentacles.
This station is a curated way to explore the species, not a claim that it stays at one exact depth.
Say hi to Clown anemonefish.
Choose a depth—sunlit reef down to deep water—or let Any water pull from all 349 fish at once.
Hit the button and the random fish generator deals a species you haven't just seen: photo, feeding note and the adaptation that earns its spot.
Open the full species profile, follow the ecology source, or remix the fish into an imaginary hybrid creature.
The ocean is continuous and rivers connect changing habitats. The stations keep the random fish generator legible; they do not replace a species range map.
Coral, lagoon and tide-pool specialists
surface–50 m
Fish from current, floodplain and still water
rivers & lakes
Seagrass, mangrove and rocky-bottom fish
shore–200 m
Wide-ranging fish that cross exposed water
pelagic water
Low-light fish of slopes, caves and cold depth
usually 200 m+
A streamlined shark trades manoeuvrability for efficient forward travel; a ray's flattened disc works near the bottom; a seahorse sacrifices speed for precision around structure.
A forward mouth often captures prey ahead, an underslung mouth works near the substrate, and a long tube can reach tiny food in narrow spaces. Treat it as a clue, not a complete diet.
Reef colour can signal or camouflage among complex backgrounds. In dim water, reflective tissue, large eyes or bioluminescence can matter more than colour visible to us at the surface.
Most random fish generators shuffle a plain list of names. This one treats every species like a small field report.
Every result is an openly licensed photograph from Wikimedia Commons, with the photographer and licence named right on the card—no clip art, no AI fakes.
Each fish is filed by the water it actually works in, from sunlit reef to deep slope, so a random draw always comes with its ecological context.
Every species carries one adaptation note drawn from an ecology source such as FishBase, NOAA or its Wikipedia article—the why behind the body you're looking at.
Any fish can jump straight into the hybrid creature generator and lend its fins, jaws or glow to something that has never existed.
Try the loop: reveal a fish above, hit Remix this fish, and it drops straight into the hybrid creature generator as raw material.
A few residents you might pull on your next try—each links to a full species page.
The reef classic that naps in stinging tentacles
The warm-muscled headliner of open water
A glowing stripe built for tea-dark rivers
The fish whose fathers give birth
A plankton-sifting glider up to 7 m wide
The fish that traded its eyes for cave senses
Possibly the longest-lived vertebrate on Earth
Steals neat round bites from tuna and whales
Three small recipes that turn one random fish generator result into something you made.
Reveal a fish and sketch only its outline—no peeking at the notes. Then read its adaptation and add that single detail to your drawing: the flatter belly, the longer snout, the bigger eye.
Pick the Sunlit reef station and study your fish's colours. Now switch to Deep water and reveal again. What changed once the sunlight ran out—the eyes, the colours, the body shape?
Every card links to the real ecology page behind it. Open the link and hunt for one fact the card doesn't show. Found one? That's genuine fish research.
It draws from 349 real fish. Each one is assigned to a useful exploration station—reef, freshwater, coast and shelf, open ocean, or deep water—based on a species-specific ecology source (FishBase, NOAA or the species' Wikipedia article) rather than the broad placeholder habitat field in the larger library.
Dive log sources
Every station entry has its own ecology link. These collections provide the shared research and photo trail behind the generator.
Species summaries used for range, depth and feeding checks in the original curated dive stations.
Primary US federal species background used for the white shark and marine ecology context.
Species articles behind the expanded pool; every such result links its exact article as the ecology source.
Source of the openly licensed photographs; each result preserves its exact credit and source URL.
Same idea, different animals.
