But, all mammals are animals. "Animals" are creatures in the Kingdom Animalia, which includes vertebrates (mammals, birds, reptiles, amphibians, and fish), arthropods (insects, centipedes and millipedes, spiders and scorpions, and shrimps and crabs), mollusks (octopuses, snails, and clams), echinoderms (starfish, sand dollars, and sea urchins), and jellyfish, and sponges, and more different kinds of worms than you could imagine, as well as several microscopic animals. We often wrongly think of "animals" as referring only to mammals, when in fact bugs and slugs, and spiders and snakes are animals, too.
