# Animals That Start With H

> This is WARN’s list of animals that start with H — 26 sourced wildlife guides from the hammerhead shark to the hyena. 8 of those guides sit in an IUCN threatened category (Critically Endangered, Endangered or Vulnerable). The list is WARN’s published library, not a census of every H-animal on Earth. WARN funds partners in 17 countries; overlap with a range is geography, not a letter grant.

## In brief

Browse 26 animals that start with H in WARN’s free wildlife-guide library. Hammerhead Shark, Hamster, Hare, Harpy Eagle and 22 more each open a sourced guide. This is not a catalogue of every species whose English name begins with H.

## At a glance

- 26: H guides
- 8: IUCN threatened on this letter
- 491: Guides in the full A to Z
- 26: Letters with WARN guides

Threatened counts follow each guide’s IUCN category (Critically Endangered, Endangered or Vulnerable). Group guides may use a status label when one badge would mislead. This is not a census of all animals.

## This is not the right page if you want

- A complete list of every animal on Earth that starts with H. WARN currently publishes 26 guides for this letter, not a zoological census.
- To look an animal up by any letter. That encyclopaedia is /animals-a-z/.
- To adopt a dog or cat into your home. WARN does not rehome pets — that is /directory/.
- A named animal with photo updates. Symbolic adoption is /adopt/; monthly sponsorship is /sponsor/.
- To donate without browsing this letter. That is /donate/ or /appeals/.
- Gift Aid or a UK charity receipt from WARN — that is /about/registration-status/.

## How to use the animals that start with H list

Stay on this page to scan WARN’s 26 wildlife guides whose common name starts with H. Confirm you want a sourced species guide, not a local pet. Then open a name, read the IUCN context, and give at /donate/ if you also want to fund partner-led rescue.

1. **Confirm you want this letter** — Stay here if you searched “animals that start with H” or need Hammerhead Shark, Hamster, Hare, Harpy Eagle and 22 more. If you wanted every letter, open /animals-a-z/. If you wanted a rescue shelter for dogs near you, stop and open /directory/.
2. **Scan the named guides** — The table lists each common name, scientific name and IUCN label from the guide. Counts are WARN guides, not species in nature.
3. **Open the sourced wildlife guide** — Each name opens a wildlife guide with facts, IUCN context, habitat, threats and FAQs. Group guides say when one Red List badge would mislead.
4. **Give if you want to fund rescue** — This letter page is an encyclopaedia, not a checkout. Use /donate/ or pick an appeal that matches the animal you just read about. You do not get a named animal. Gift Aid is not available.

## What animals start with H?

Animals that start with H, in WARN’s library, are Hammerhead Shark, Hamster, Hare, Harpy Eagle and 22 more. There are 26 sourced wildlife guides on this URL. The heading matches the search; the inventory matches the guides.

The query family is “animals that start with H”. This URL exists so that query has its own page, instead of a hash on /animals-a-z/. Other letters have the same pattern at /animals-that-start-with-a/ through /animals-that-start-with-z/.
Sorting uses the common name. Scientific names still appear in the table. Hammerhead Shark is first on this letter because of English spelling, not because it is more important than Hyena.

## How many animals start with H?

WARN currently publishes 26 wildlife guides whose common name starts with H. 3 are listed as Critically Endangered. 8 sit in an IUCN threatened category.

Those numbers count WARN guides, not life on Earth. A group guide still occupies one slot. When WARN publishes another H-animal, the count on this page will move.
The A to Z hub at /animals-a-z/ holds 491 guides across the alphabet. This letter is 26 of that library.

## Is this every animal that starts with H?

No. This page indexes 26 WARN guides, not every species whose English name begins with H. Missing from the list means the guide is not published yet — not that the animal does not exist.

Search engines still send “list of animals that start with H” to pages like this. The honest answer is the count on the page. IUCN has assessed tens of thousands of animal species; this site publishes a curated, sourced subset.
For the full WARN index, use /animals-a-z/. For extinct animals WARN has covered, use /wildlife-guides/extinct-animals/.

## Does WARN rescue animals that start with H?

Not as a letter. Many of these guides are educational. WARN funds rescue and conservation partners across 17 countries. Each H-guide notes where WARN is, and is not, currently active.

A heading that implied every listed animal has a WARN field team would be a lie. Reading a guide is free either way. If you want to fund partner-led work, that is /donate/ or /appeals/.
You do not get a named hammerhead shark from a gift. Entry-tier gifts pool across the programme.

## How are animals that start with H sourced?

Each guide’s facts are checked against the sources on that page — IUCN Red List and CITES where status and trade listings apply. This letter page does not invent counts the guides do not support.

Do not treat a letter heading as an IUCN assessment. The assessment lives on the species page. Editorial standards, corrections and AI disclosure live at /about/editorial-standards/.
Markdown twins of this letter sit at /llm/animals-that-start-with-h.md for answer engines.
