Built for real situations

Designed around the moments when identification matters.

"After a dive, I want my photo to suggest the right species so I can learn and log it."

Photo identification

Look-alike clarity

"Before a trip, I review past sightings so I can find them again."

Trip prep

What is a fish identifier app?

A fish identifier app combines photo suggestions with guided trait filters so you can name species even if you only remember colors or fin shapes. Drop in a picture or select traits such as body profile, tail type, or habitat and the Fish Identifier by Seabook surfaces likely matches while pointing out subtle look-alike differences.

Seabook extends beyond the ID by keeping Catch and Dive Logs together. Measurements, gear, depth, water conditions, and GPS (when permitted) live alongside your photos, while custom collections keep target lists, study sets, or class references organized.

  • Use photo suggestions plus trait filters for fast IDs
  • Compare similar species with highlighted differences
  • Log catches and dives with notes, media, and locations
  • Organize collections for trips, study sessions, or favorites

How to identify a fish from a photo (step-by-step)

Follow these quick checks to narrow the species before logging it in Seabook.

  1. Note region & habitat (reef, wreck, estuary, lake) to limit the catalog.
  2. Check body profile (elongated, deep-bodied, eel-like) for instant clues.
  3. Inspect color & pattern (bars, spots, stripes, blotches) that stand out.
  4. Look at fins & tail (forked vs. rounded tails, dorsal fin breaks, filament tips).
  5. Compare distinctive marks (eye lines, fin spines, head bumps) that set species apart.
  6. Use the trait filters to narrow candidates and confirm with photos.

Common look-alikes explained

Parrotfish vs. Wrasse beak-like mouths and heavier head profiles suggest parrotfish.

Snapper vs. Redfish/Drum — canine teeth and a sloped head hint snapper; a spot near the tail suggests red drum.

Grouper vs. Rockfish — grouper usually show deeper bodies and large mouths, while rockfish display prominent dorsal spines.

Frequently asked questions

Answers to what anglers, divers, and ocean lovers ask most.

Does this help anglers?

Yes. Confirm species from a photo, then save every catch with measurements, lure, and spot details.

Can I identify fish without the name?

Yes. Use trait filters like color, pattern, fin & tail shape, body type, habitat, and region.

Freshwater and saltwater?

Yes. The catalog covers many common freshwater and marine species, with more added regularly.

Is there a dive log?

Yes. Record location, depth, notes, and species to review later.

Can I make my own collections?

Yes. Build trip targets, study sets, and favorites.

Does it work offline?

Yes. Enable offline mode to keep your logbook and the traits catalog available without a connection.

Will my data sync?

Yes. Sign in to sync logs and collections securely to the cloud.
