Frequently asked questions
| Question | Answer |
|---|---|
| How does the random animal generator work? | It picks an animal at random from a list of 120 animals using your browser's cryptographic random generator, so every animal in your filter has the same chance. Each result shows the animal, its scientific name, diet, habitat and a fun fact. |
| Which animal classes are included? | Mammals, birds, reptiles, amphibians and aquatic animals. Aquatic covers fish, sharks, rays and water-dwelling invertebrates such as octopuses, squid, jellyfish and lobsters. Whales and dolphins are listed under mammals, and sea turtles under reptiles. |
| Can I filter by diet or habitat? | Yes. Besides the class, you can choose a diet type such as carnivore, herbivore, omnivore, insectivore, piscivore, filter feeder or nectarivore, and a habitat such as rainforest, desert, ocean or polar regions. |
| Where do the fun facts and photos come from? | The facts are short, general-knowledge statements written for this tool. Photos are loaded from Wikipedia when available and credited to it; if a photo cannot load, the animal's emoji is shown instead. |
| How do I share a class or a result? | Open or share a link such as ?class=mammal to start the generator with mammals selected. After you generate, copy the first link to share exactly the animals you got, or the filter link to share your class, diet and habitat choices. |
| How many animals are included? | The list has 120 animals: 30 mammals, 25 birds, 22 reptiles, 15 amphibians and 28 aquatic animals. It is a curated selection of well-known species, not a complete catalogue of animal life. |
