An animal is a Animals (also called Metazoa) are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from 8.5 micrometres (0.00033 in) to 33.6 metres (110 ft). They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.
Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing invertebrates such as nematodes, arthropods, and molluscs, and the deuterostomes, containing the echinoderms and the chordates, the latter including the vertebrates. Life forms interpreted as early animals were present in the Ediacaran biota of the late Precambrian. Many modern animal phyla became clearly established in the fossil record as marine species during the Cambrian explosion, which began around 542 million years ago.

The creatures living among us, who needs to be treated better. A lot of them are dying right now, mostly because of wildfires, but also because of the lack of treatment us humans give them (hurting them). Some of them are even beginning to become instinct, which is extremely sad since they were on this planet first. ah hah ha just saying-

If black people think white people seem to care more about animals than people, it's not personal, animals are innocent and don't participate in their own undoing or the undoing of other animals. They know nothing of betrayal, jealousy, hatred, cruelty, or trickery.
Animals are good natured. People aren't really good or bad by nature, they're just people. They're not innocent like horses, dogs, cats, monkeys, lions, fish, sharks, whales, octopus, squid, birds, bees, or any other animals.
