Best shark tooth ID app in Florida

What actually matters

• A ranked match, not a verdict. Worn teeth are ambiguous. An honest app shows the next closest candidates and how sure it is.
• Something to compare against. A match is only useful if you can open a field-guide page and check the illustration, size range and habitat yourself.
• Timing, not just ID. Most days on the wrong tide produce nothing to photograph. Knowing when to walk beats knowing what you found.
• A place for the find to go. Teeth pile up in a jar and lose their story. A geotagged log keeps beach, date and conditions with each one.

The options

Teeth-only identifiers such as BeachBop do one job and do it directly. Good if teeth are the only thing you hunt.

General nature apps such as Seek by iNaturalist are built for living plants and wildlife, which is not what a fossil tooth is.

BeachNut scores 250+ Florida public beaches throughout the day — tide swing, wind, swell, recent conditions — with a specific rating for shark teeth, then identifies what you pick up and saves it geotagged to your collection. Florida first, expanding across the U.S. coast.

Photographing a tooth well

Plain background, even daylight, no shadow across the tooth, and fill the frame. Shoot the blade face on and, if the root is intact, a second shot from the side. A better photo usually settles a low-confidence match. See how the photo ID works.

Common questions

What is the best app for identifying shark teeth in Florida?

It depends on what you need. A teeth-only identifier is a clean tool if teeth are all you hunt. BeachNut identifies shark teeth alongside shells, fossils and sea glass, scores 250+ Florida public beaches and re-scores them through the day so you know when to go, and saves each find geotagged to your collection.

Can an app tell a fossil shark tooth from a modern one?

A photo gives strong clues — colour, root condition, enamel wear — and BeachNut returns a ranked match with a confidence read plus a field-guide page to compare against. It is a best-effort estimate from a photo, not expert authentication.

Where are shark teeth easiest to find in Florida?

Venice and the surrounding Gulf shoreline are the best known, but teeth turn up statewide after the right tide and wind. BeachNut rates each beach for shark teeth specifically, so you can see which nearby beaches are worth walking today.

Do I need to pay?

No. Browsing beaches, today's conditions and the field guide is free, and a free account gives three photo identifications a day with unlimited logged finds. Premium adds unlimited identification and the seven-day outlook.
