Habitat & range
Where it lives, its depth and water type, and how far its range extends across the world’s waters.
How to identify
Key field marks, fin shapes, and colour patterns — plus the look-alike species people commonly confuse it with.
Personal collection

How it works
From photo to fish ID in seconds
- Step 01
Take a photo
Capture the fish in good light — a clear side-on shot of the body and fins is all the AI needs.
- Step 02
AI does the ichthyology
Our model reads body shape, fin structure, and colour patterns to identify the species.
- Step 03
Read the report
Get the name, classification, habitat, behavior, and how to tell it apart from similar fish.
