About WildFacts
Our mission
What does an orca eat? How long does a sea turtle live? How big is a blue whale next to a person? WildFacts answers questions like these with real numbers from scientific and government sources, written so that curious adults, parents and students can all use them. Where scientists disagree or numbers vary, we show the range and say why.
What we cover
- Animal profiles. The key facts about an animal: size, lifespan, diet, where it lives and its conservation status.
- Diet and lifespan guides. Deeper answers to "what do they eat" and "how long do they live", with wild and human-care numbers kept apart.
- Tools. A Size Comparison drawn to true scale and an Animal vs Animal data comparison. We compare real measurements only; we do not guess who would win a fight.
We start with ocean animals and will add rivers and lakes, polar regions, rainforests, deserts and grasslands over time.
Where our information comes from
We rely on NOAA Fisheries, the U.S. Fish and Wildlife Service, the Smithsonian, Animal Diversity Web (University of Michigan), Monterey Bay Aquarium's animal guides and peer-reviewed research. For conservation status we name the IUCN Red List category and link to the Red List. Every article lists its sources at the bottom; see our editorial policy.
About our images
Animal pages use real photos that are in the public domain or released under Creative Commons licenses that allow reuse; each is credited under the photo and on our photo credits page. The ocean and habitat illustrations on the home page are made for this site with AI image tools. Charts and diagrams are drawn by us from the cited sources.
Independence
WildFacts is an independent site. It is not affiliated with NOAA, the Smithsonian, any aquarium, zoo or university we cite. The site is supported by advertising and, where noted, affiliate links; see our affiliate disclosure.
Frequently asked questions
Can I use WildFacts for school work?
Yes. For a report, we suggest citing the original sources listed at the bottom of each article, which is what teachers usually ask for.
Why do your numbers differ from another website?
Animal sizes and lifespans vary by population and by study. We give ranges from named sources and keep wild and human-care figures separate.
