Entries may cover a species, a group or a domestic breed. Conservation labels reflect the assessments cited in each guide. ## Find the animal you are curious about Start with a name, a letter or a question. You can combine filters and share the resulting link. 1. **Search a name or choose a letter** — Try a common name such as orangutan or a scientific name such as Pongo. Letter pages collect animal names beginning with each letter of the English alphabet. 2. **Narrow your discoveries** — Choose an animal group, region or conservation status. Filter counts change as you narrow the list. Clear a filter to broaden your results again. 3. **Read the guide and its sources** — Open a card for identification, habitat, diet, behaviour and conservation information. Check whether it describes a single species or a wider group, and follow the references for the evidence behind a fact. ## Common names, scientific names and animal groups A common name is the everyday name of an animal. A scientific name helps identify the species more precisely. Some familiar names, such as bear or parrot, describe several species. Common names vary between languages and places. A name can also refer to different animals in different contexts. When you compare facts, check the scientific name and the location as well as the heading. Search accepts both common and scientific names so you can begin with whichever you know. A broad group guide gives an overview and introduces its members. A species guide can be more specific about range, diet and conservation. Domestic breeds are another kind of entry: a breed is not a separate wild species. These entries each count as one guide in this library. For closely related or easily confused animals, explore /compare/. A side-by-side comparison is useful when you want to understand identification features rather than read two separate overviews. ## How to read animal facts in context Size, lifespan, diet and behaviour need context. Check whether a figure describes an adult or a juvenile, a typical range or an exceptional record, and animals in the wild or in human care. A maximum weight does not describe every individual. Males and females may differ, and measured populations may live in different conditions. When a guide gives a range, read the explanation alongside it before using a single number in schoolwork or a comparison. Diet describes what an animal eats, while habitat describes where it lives. Behaviour can change with season, age, breeding and food availability. Details from one species should not automatically be applied to every animal in its group. Looking for a particular term? /wildlife-guides/baby-animal-names/ explains names for young animals, and /wildlife-guides/animal-group-names/ covers collective nouns. /answers/ offers focused explanations of common animal questions. ## Explore animals by habitat and region An animal’s range is the area where it occurs; its habitat is the environment it uses within that area. The region filter offers a starting point, while individual guides explain the detail. A broad label such as Asia does not mean an animal lives throughout the continent. Island populations, migration routes and small remaining ranges can be especially important. Read the guide’s distribution section to understand where the animal is found. Forest, wetland, grassland and ocean habitats support different communities of animals. Some species use more than one habitat during their lives. Habitat loss, fragmentation and changes in food or water can affect them differently. Use /wildlife-guides/ to explore themed collections, including /wildlife-guides/animals-in-asia/ and /wildlife-guides/animals-in-south-america/. Those collections offer another way to discover the same guide library. ## What do conservation status labels mean? The IUCN Red List assesses extinction risk. Vulnerable, Endangered and Critically Endangered are the three threatened categories. They describe risk, rather than the number of animals a rescue organisation is caring for. In this library, 22 guides carry a Critically Endangered label and 110 carry one of the three threatened labels. These are guide counts, not a count of all threatened species worldwide. A group covering several species may need a mixed-status explanation. A global assessment and a local population can tell different stories. Read the named assessment and its date in the species guide. Data Deficient means there is insufficient information for a full assessment; Not Evaluated means the species has not been assessed against the criteria. Neither label establishes that an animal is safe. CITES addresses international wildlife trade. Its listings have a different purpose from IUCN extinction-risk categories. See /wildlife-guides/critically-endangered-animals/ for a focused collection, and /wildlife-guides/animals-threatened-by-wildlife-trafficking/ for the trade context. ## Check the evidence behind an animal guide Use the references on the individual guide to trace a claim to its source. The date on this index reflects updates to the library; it does not mean every species assessment was published on that date. Conservation assessments, scientific research and specialist animal organisations answer different questions. IUCN provides extinction-risk assessments, CITES provides trade information, and the references on a guide support its other factual claims. A source should support the particular statement being made. For school projects or further research, record the species name, source and publication or assessment date. If sources differ, check whether they describe different populations, periods or methods before treating one figure as definitive. Our sourcing and correction approach is explained at /about/editorial-standards/. If you spot an error or an outdated reference, use /contact/ and include the page link and the information that needs checking. ## Turn curiosity into help for animals Learning, sharing reliable information and supporting a relevant appeal are all ways to help. An animal’s inclusion in this library is educational; it does not establish that WARN has a rescue project for that animal. Share a guide when it can correct a misconception or help someone understand a conservation issue. Choose responsible wildlife experiences, and avoid activities that depend on handling wild animals or purchasing wildlife products. If you would like to donate, read /appeals/ for the purpose and terms of each fund, and /about/where-your-money-goes/ for how funding decisions are explained. The Kalimantan appeal at /appeals/kalimantan-wildlife-fires/ sets out its evidence and the process for selecting recipients. For an injured animal, use /rescue/ to find appropriate next steps. For local pet adoption or nearby organisations, explore /directory/. ## Frequently asked questions ### How many animals are in the A to Z index? The index contains 491 published guides across 26 letters. Entries include individual species, wider animal groups and selected domestic breeds, so this is a guide count rather than a species count. ### Is this a complete list of every animal in the world? This is a growing collection of WARN guides. Many animals do not yet have an entry. You can suggest a missing animal through /contact/. ### How do I find animals beginning with a particular letter? Choose a letter to filter the search results, or open one of the letter pages below the browser for a list with links to each guide. For example, /animals-that-start-with-a/ lists names beginning with A. ### Can I search for an animal by its scientific name? Yes. The search includes common and scientific names. You can also combine a search with animal-group, region and conservation-status filters. ### How can I find endangered animals? Choose Endangered or Critically Endangered in the conservation-status filter. Vulnerable is also a threatened category. For a collection with context, explore /wildlife-guides/most-endangered-animals/. ### Are animal guides free to read? Yes. The animal guides are free to read. Donations are optional; appeal pages explain their purpose, terms and funding arrangements. ### Are there animal guides in German, French and Spanish? Selected animal guides are available at /de/tiere/, /fr/animaux/ and /es/animales/. Their A–Z directories also link to the larger English library, with the language of those guides identified. ### Does WARN rescue every animal in the index? The library is educational and covers many animals beyond the scope of individual appeals. Read the relevant appeal for confirmed activities, funding plans and recipient information. ## Sources - [IUCN Red List categories and criteria](https://www.iucnredlist.org/resources/categories-and-criteria) — How extinction-risk categories are defined - [IUCN Red List summary statistics](https://www.iucnredlist.org/resources/summary-statistics) — Assessment coverage and how to interpret totals - [CITES species checklist](https://checklist.cites.org/) — International wildlife-trade listings - [WARN editorial standards](https://worldanimalrescuenetwork.org/about/editorial-standards/) — Sources, corrections and editorial practice
