How it works
This list holds 126 living mammals you may not have met, from the Philippine tarsier to the Fin whale. Press Pick 5 new mammals: each card gives its kind, where it lives and one checked fact.

Pick a kind
The list beside the button reads Any kind. Choose Primates (15), Carnivores (22), Hoofed mammals (20), Rodents and rabbits (18), Bats (10), Pouched and egg-laying (13), Whales, seals and manatees (14) or Insect-eaters and oddballs (14). Seals sit with the whales, not the carnivores.
Guess the kind
Open More options and press Hide all facts. Read each name and call its kind before you press Show facts: a Fossa is a carnivore, a Rock hyrax is a relative of elephants, and a Sunda flying lemur is not a lemur.
Tips
- Change Show 5 to Show 20 and sort the twenty by size, from the Etruscan shrew to the Fin whale.
Questions and answers
Why are lions and elephants missing?
They are on the random animal generator. This page holds only mammals that list does not, so a random mammal here is one you are less likely to know.
What makes an animal a mammal?
Mammals feed their young on milk and have hair or fur at some stage of life. Most give birth to live young; the echidnas and the platypus lay eggs.
Are the facts checked?
Yes. Every scientific name was matched to a mammal species on GBIF on 23 September 2026, and every fact line was checked against the animal's Wikipedia article the same day.
