Animal
Animals are a major group of multicellular, eukaryotic organisms of the kingdom Animalia or Metazoa. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their life. Most animals are motile, meaning they can move spontaneously and independently. All animals are also heterotrophs, meaning they must ingest other organisms or their products for sustenance.

—Dalton Trumbo (1905–1976)
“The most threatened group in human societies as in animal societies is the unmated male: the unmated male is more likely to wind up in prison or in an asylum or dead than his mated counterpart. He is less likely to be promoted at work and he is considered a poor credit risk.”
—Germaine Greer (b. 1939)
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
