BeachNut vs Seek

Seek by iNaturalist points a camera at all of nature. BeachNut points one at the tide line in Florida.

The short version

Seek is excellent at what it is for: living plants and wildlife, anywhere in the world, feeding a global naturalist community. If you want to know the bird on the dune or the plant behind it, use Seek.

Most of what you pick up on a beach is not a living organism. It is an empty shell, a fossil tooth, a tumbled piece of glass, a drift seed, a shard of old pottery. BeachNut is built for that pile — and for the question that comes first: is today even worth the drive?

Where they differ

  • Subject. Seek: living organisms everywhere. BeachNut: beach finds — shells, shark teeth, fossils, sea glass, sea beans, beach pottery.
  • Timing. Only BeachNut scores beaches daily and names the best window to walk.
  • Place. BeachNut covers 250+ Florida public beaches with maps, nearby search, a day planner and local collecting rules.
  • Keeping. Finds save to a geotagged collection with beach, date and conditions attached.
  • Scope. BeachNut covers Florida public beaches today and is expanding across the U.S. coast. It is not a plant or rock identifier.

How the ID works

You get a ranked match — most likely first, then the next closest candidates — each with a confidence read, and every match links to its field-guide page so you can compare against the illustration, size range and habitat yourself. Markings and exact colorations vary between individuals. Identifications are best-effort estimates from a photo, not expert authentication.

Common questions

Can Seek identify shells and shark teeth?
Seek is built around living organisms across all of nature. Beach debris like worn shell fragments, fossil shark teeth, sea glass and beach pottery sit outside what a living-organism identifier is designed for.
What does BeachNut identify?
Shells, shark teeth, fossils, sea glass, sea beans and beach pottery, returned as a ranked match with a confidence read and a link to the field-guide page for that species or material.
Does BeachNut tell me when to go to the beach?
Yes. BeachNut scores 250+ Florida public beaches and re-scores them through the day using tide swing, wind, swell and recent conditions, and gives the best window to walk.
Is BeachNut free?
Browsing beaches, today's conditions and the full field guide is free. A free account logs unlimited finds with three photo identifications a day. Premium adds unlimited identification, the seven-day outlook and multi-day trip planning.
