What is meant by extinct animal?

Extinct animal refers to a species of animal that no longer exists on Earth, meaning that there are no living individuals of that particular species. Extinctions can occur for various reasons, including natural causes such as habitat loss, climate change, and competition with other species, as well as human-related factors such as overhunting, habitat destruction, and introduction of invasive species. Some examples of extinct animals include the dinosaurs, woolly mammoths, saber-toothed cats, and the dodo bird.
