Any of the multicellular organisms belonging to the kingdom Animalia. All animals are eukaryotes, with each of their cells having a nucleus containing DNA. Most animals develop from a blastula and have a digestive tract, nervous system, the ability to move voluntarily, and specialized sensory organs for recognizing and responding to stimuli in the environment. Animals are heterotrophs, feeding on plants, other animals, or organic matter. The first animals probably evolved from protists and appeared during the Precambrian Era.
A brutal or aggressive person, esp one given to excessive sexuality or violence (1940s+ Army & students)
an organized living creature endowed with sensation. The Levitical law divided animals into clean and unclean, although the distinction seems to have existed before the Flood (Gen. 7:2). The clean could be offered in sacrifice and eaten. All animals that had not cloven hoofs and did not chew the cud were unclean. The list of clean and unclean quadrupeds is set forth in the Levitical law (Deut. 14:3-20; Lev. 11).
