What is a fish identifier app?

A fish identifier helps you recognize species using visual clues from your photos or from a trait search when you only remember color, pattern, or fin shape. Seabook suggests likely matches and highlights traits such as color bands, body shape, fin and tail patterns, and common habitats-perfect for anglers on the dock, divers underwater, or anyone comparing similar species.

Beyond the ID, Seabook acts as a catch log and dive log. You can store tackle or gear details, capture GPS (when allowed), and save notes about depth or water conditions so every catch or sighting is recorded for future trips, classes, or research.

With Seabook, you can:

  • Identify fish from your own photos or trait filters
  • Compare similar species side by side with highlighted differences
  • Keep a dedicated Catch Log and Dive Log with locations and notes
  • Learn about marine life behaviors, traits, and habitats
  • Build personal collections to share with buddies, captains, or classmates
