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.

Famous quotes containing the word animal:
“There is no mystery in the luminous lines
Of that high, animal face
The smile, sad, humouring and equal
Blesses without obliging
Loves without condescension;”
—Denis Devlin (1908–1959)
“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)
“When we reflect upon the cruelties daily practised upon such of the animal creation as are given us for food, or which we ensnare for our diversion, we shall be obliged to own that there is more of the savage in human nature than we are aware of.”
—Samuel Richardson (1689–1761)
