An encyclopedia with field boots on

FrogWorld began in 2009 as a hobbyist forum where a few dozen frog enthusiasts traded photos and identification guesses. It became something more serious when its contributors realized the community was producing data: thousands of geotagged sightings from places no researcher would visit that year. Today FrogWorld pairs a reviewed species database with that living field record — built by amphibian obsessives, structured like a scientific reference.

What the site offers

Everything is built to answer one question well: what did I see, and what is known about it?

• A species database covering the world's frog and toad families, with identification keys, habitat notes, and conservation status for each entry.
• A community sightings log of tens of thousands of geo-tagged records, each reviewed by a regional herpetologist before it earns verified status.
• Interactive range maps built from verified sightings, honest about gaps — an empty region means nobody has logged data, not that the species is absent.
• Call recordings and spectrograms, because for many species the ears identify faster than the eyes.

Our standards

Identification is where most nature sites go soft, so we go the other way: uncertain sightings stay marked uncertain, reviewers can challenge their own earlier verifications, and species data cites its sources. We support ethical field practice — no handling, no habitat disclosure for threatened populations, and no trade of any kind.

Whether you are a first-time frog-spotter in the tropics or a researcher tracking disease in wild populations, FrogWorld is built to be the reference you can check and the community you can contribute to — one verified sighting at a time.
