Terms of use
Plain terms for a reference site. By using CreatureData you agree to them.
Last updated 11 November 2026
Using the site
CreatureData is free to read. You may link to any page, quote from it with credit, and print pages and checklists for your own or classroom use.
Reusing facts, photos and text
- Facts and figures come from open datasets and may be reused under each dataset’s licence, listed on the sources page.
- Photos and recordings belong to their creators and are shown under the licence printed beside each one. To reuse one, follow that licence and credit the creator, not CreatureData.
- Quoted passages from Wikipedia are under CC BY-SA and must keep their attribution and licence.
- Our own text and design, including page summaries, the glossary and the logo, belong to CreatureData. You may quote the text with a link back.
To cite a page, use the citation given at the foot of each species page.
What the site is not for
CreatureData is a general reference. Do not rely on it to decide whether an animal is dangerous, venomous, safe to handle or safe to eat, or for veterinary, medical or legal decisions. The “What did I see?” tool narrows possibilities; it does not identify an animal.
Accuracy
We take facts from named sources and show where each came from, but sources contain errors and gaps, and sighting records are not range maps. The site is provided as it is, without any guarantee that it is complete, correct or always available. To the extent the law allows, CreatureData is not liable for loss arising from reliance on it. Nothing here limits liability that cannot be limited by law.
Fair use of data access
The JSON and Markdown versions of pages are free to use. Please cache what you fetch and keep to a few requests a second. Automated use that degrades the site for others may be blocked. Search engines and AI crawlers are welcome within the limits set in robots.txt.
Embedded cards
You may embed species cards on your own site using the code provided, unaltered, so that the photo credit and the link back remain visible.
Your lists
Lists and sightings are stored in your browser, not by us. Keep your own copy using the export on the My lists page; we cannot recover them if your browser data is cleared.
Changes and law
These terms may change; the date at the top shows when they last did. They are governed by the law of England and Wales.
