Species and lifespans: Myhrvold et al. (2015) amniote life history database (CC0). Continents: GBIF occurrence records (gbif.org).
How to use the random animal generator
Pick the well known animals list for famous species that everyone can picture, or switch to all species to discover animals most people have never heard of. Choose a continent, a habitat or an animal group, then press Pick a random animal. Leave No repeats ticked if you want every animal to appear once before the list starts again, which is useful for classroom games and quizzes.
Random animal wheel
Prefer a spinner? Press Spin the animal wheel and the generator fills a wheel with ten animals from your current filters, spins it and lands on your random animal. It works like an animal wheel spinner for classrooms, parties and live streams, and every animal on it is a real species with facts about where it lives.
Where the data comes from
The species list and lifespans come from the amniote life history database by Myhrvold and colleagues, published in Ecology in 2015 and released under a CC0 licence. Continents come from occurrence records shared through GBIF, the Global Biodiversity Information Facility, which brings together millions of museum specimens and field observations. A continent is listed when a species has a meaningful number of records there, so rare strays and zoo animals are left out. Habitats for the well known animals were added by hand by an ecologist.
Because the data depends on where people record wildlife, some species with very few records show no continent, and a small number of introduced populations are included. The generator covers mammals, birds and reptiles.
Ideas for using it
Teachers use it to set research tasks, where each student draws an animal and presents its habitat and adaptations. Artists use it for daily drawing prompts. Families use it for guessing games on long journeys, and wildlife lovers use it to pick the next species to read about. The all species mode is a great way to learn how many little known mammals, birds and reptiles share the planet with us.
Frequently asked questions
Are these real animals?
Yes. Every animal is a real species with a published scientific name, taken from a peer reviewed database.
How many animals are in the generator?
There are 267 well known animals and 5,184 species in total, covering mammals, birds and reptiles from every continent.
Can I pick animals from one continent only?
Yes. Use the Continent filter to limit the draw to Africa, Asia, Europe, North America, South America, Oceania or Antarctica, and combine it with a habitat or animal group.
Is it free?
Yes. The generator is free to use with no sign up, on phone or computer. Find more in our free ecology tools, including the wildlife lifespan calculator.
