What Is Animals Tribune?

Animals Tribune is a free encyclopedia of animals written for curious readers, students and teachers. Every page explains one animal, group or question in plain English, with size charts, range maps, data tables, fun facts and a short quiz, all checked against open scientific data.

We built this site to answer the questions people actually ask about animals: how big is it, where does it live, what does it eat, is it dangerous, and how does it compare with that other animal that looks just like it. Each answer comes first, in a sentence or two, and the details follow for readers who want to go deeper.

Pages follow the same clear layout, so you always know where to look. A short At a Glance box sums up the animal, a facts table lists its scientific classification and measurements, and drawings show its size next to a person. Most species pages also include a map of the US states and countries where it has been recorded.

The writing is aimed at a broad audience, from a fourth grader working on a report to an adult who just spotted something odd in the backyard. Teachers can link any page in class, and every quiz works on a phone.

How We Check Our Facts

Numbers on this site are never made up. Scientific names, family and order, typical size, weight, lifespan and conservation status labels come from open scientific databases, and where an animal lives comes from recorded sightings in open biodiversity records. For US wildlife we also rely on public information from agencies such as the US Fish and Wildlife Service, NOAA and the National Park Service. Our main data partners are Wikidata and GBIF, credited in full on our sources page.

Our editors write every page from scratch and label any typical value that is not taken straight from the data. Illustrations are created for us and diagrams, maps and size charts are drawn in code from the data, so they stay accurate. If you spot a mistake, tell us through our contact page; the full process is on our editorial policy page.
