Red List Species Intelligence

Endangered Animals & Conservation Status, Carefully Sourced

An educational, source-transparent guide to threatened wildlife. We summarise IUCN Red List categories for 223 species, link every record to authoritative references, and show exactly how current and how confident each entry is — never presenting status as permanent.

What the Red List means

The IUCN Red List of Threatened Species is the world's most widely used assessment of extinction risk. Each species is placed in a category — from Least Concern to Critically Endangered — based on transparent criteria such as population size, rate of decline, and range. The Red List is maintained by the International Union for Conservation of Nature and is updated as new science arrives.

FaunaHub is an independent educational publisher. We do not run assessments or set conservation status. Instead, we summarise published categories in plain language and link you to the authoritative source so you can verify the current status yourself.

How FaunaHub uses conservation status carefully

Verified sources only

Every record links to authoritative references — IUCN, Animal Diversity Web, NOAA Fisheries, and the U.S. Fish & Wildlife Service.

No invented data

We never invent status, population numbers, trends, threats, or ranges. Optional fields are shown only when verified.

Status is a snapshot

Categories change as species recover or decline. We date every record and point you to the live IUCN entry.

Quality over volume

Many records are index-only. We build full profiles only where there is enough verified material and a licensed photo.

Honest confidence flags

Each record carries a confidence flag so you can see how much of it has been individually re-verified.

No alarmism

This is a calm reference, not a fundraising campaign. We avoid panic language and sensational claims.

Frequently asked questions

Frequently Asked Questions

Is this the official IUCN Red List?
No. FaunaHub is an independent educational publisher. This is a source-transparent overview that links to the official IUCN Red List and other authoritative references. For current, authoritative status always use iucnredlist.org.
How current is the conservation status shown here?
Each record carries a last-verified date — the date FaunaHub last reviewed it against its sources. Status can change between reviews, so the live IUCN Red List entry is always the current source of truth.
Why doesn't every species have its own page?
Many records are index-only: they appear in category lists with their status and sources but do not get a standalone page. FaunaHub only builds a detailed profile when there is enough verified material, and ideally a properly licensed photo, to justify one. This keeps quality high and avoids thin pages.
Where does FaunaHub get its conservation data?
From authoritative sources: the IUCN Red List, Animal Diversity Web (University of Michigan), NOAA Fisheries, the U.S. Fish & Wildlife Service, the National Park Service, and museum and university references. FaunaHub does not use unsourced listicles, pet shops, or AI-generated fact pages.
Does a category like “Endangered” ever change?
Yes. As populations recover or decline and as new science arrives, the IUCN reassesses species and categories move up or down. FaunaHub presents status as a snapshot, never as permanent, and points readers to the live IUCN entry for the latest assessment.
