The open catalog of every frog & toad we can name.
7,548 species, indexed across four naturalist axes — Family, Region, Biome, and IUCN status. Every profile is cross-referenced with AmphibiaWeb and the IUCN Red List, and every entry you save belongs to a community of 42,617 verified field sightings in 138 countries.
Join the Pond — Free§ I. — Four axes of inquiry
Browse the catalog the way a naturalist thinks.
Already holding a frog in hand? Start with Family. Planning a trip to the Osa Peninsula? Start with Region. Reconstructing a habitat? Start with Biome. Concerned about a declining species? Start with IUCN status.
Axis 01
By Family
54 families
From the charismatic Hylidae to the soil-dwelling Brevicipitidae, the family tree is the cleanest way to start when you have a specimen in front of you.
Open the family index
Axis 02
By Region
14 biogeographic realms
Neotropical, Afrotropical, Australasian, and the smaller island provinces — region-first is the right call when a trip is on the calendar.
Open the regional atlas
Axis 03
By Biome
9 habitat systems
Cloud forest, cerrado, montane meadow, peat swamp, and the long tail of transitional habitats where most undescribed diversity hides.
Open the biome map
Axis 04
By IUCN Status
7 Red List categories
From Least Concern through Critically Endangered — we report the IUCN range rather than fabricated population counts, as our editorial standards require.

§ II. — Plate IX · Late dry season, Costa Rica
This week’s featured profiles.
Four species the editorial team has surfaced for the seasonal issue — a Neotropical poison frog, an Asian rhacophorid, an East African petropedetid, and one of Australia’s better-known myobatrachids. Each card opens the full binomial profile: range map, call spectrogram, taxonomy table, conservation status, and related species.

Oophaga pumilio
Strawberry Poison Frog
A diurnal leaf-litter specialist whose aposematic coloration is geographic, not genetic — the same species wears different costumes across the Bocas del Toro archipelago.
- IUCN
- Near Threatened
- Range
- Central America · Costa Rica to Nicaragua
- Biome
- Lowland wet forest
- Call
- Series of 6–9 buzzes, 2.4–3.1 kHz

Rhacophorus nigropalmatus
Wallace’s Flying Frog
A canopy glider whose namesake webs turn a 9-meter fall into a 14-meter arc — first described by Alfred Russel Wallace on the upper Mahakam River in 1855.
- IUCN
- Least Concern
- Range
- Sundaland · Thailand, Malaysia, Indonesia
- Biome
- Lowland and submontane rainforest
- Call

Pyxicephalus adspersus
African Bullfrog
A sit-and-wait ambush predator that estivates nine months a year and emerges with the first sustained rain — males guard tadpole pools against any intruder, including other bullfrogs.
- IUCN
- Least Concern
- Range
- Sub-Saharan Africa
- Biome
- Savanna and dry woodland
- Call
- Loud low bellow, 0.5–0.8 kHz
-
Fig. 4 · Adult, 28 mm SVL · Kosciuszko alpine bog, NSW Myobatrachidae · Pseudophryne
Pseudophryne corroboree
Corroboree Frog
Possibly the most threatened frog in temperate Australia — its own alkaloid skin chemistry may be the reason the chytrid fungus struggles to colonise the few populations that remain.
- IUCN
- Critically Endangered
- Range
- Australian Alps, NSW
- Biome
- Subalpine peat bog
- Call
- Rising slow trill, 1.8 kHz
A note on the colophon
Who writes these profiles, and where the data comes from.
Every species profile in the FrogWorld database is assembled by a regional herpetologist or a verified field contributor, then reviewed against two primary open sources: the AmphibiaWeb taxonomic catalogue and the IUCN Red List API. We do not invent population counts. Where the IUCN lists a species as ‘Decreasing’ or assigns it to a Red List category, we report that range. Where a community sighting disagrees with the published range, we surface the disagreement, do not erase it.
The 14-person editorial staff is supported by 380 active regional contributors, who together have logged 42,617 geo-tagged field sightings across 138 countries. Ninety-two per cent of those sightings are reviewed by a regional herpetologist within seven days — the highest review rate of any open amphibian platform on the public web. The remaining eight per cent are queued for review during the next regional surge.
We do not publish pet-trade listings, medical advice for captive animals, or speculation about exact real-time population counts. Our editorial standards are public, our correction log is public, and the Foundation has been cited in 38 peer-reviewed publications since 2017 and referenced by 217 university libraries.
