Animalia ( Kingdom )

Animalia

"Eucaryotic multicellular organisms. Their principal mode of nutrition is by ingestion. Many animals are motile, and they generally lack the rigid cell walls characterized by plants. Considerable cellular migration and reorganization of tissues often occuring during the course of embryology. Their reproduction is primarily sexual, with male and female diploid organisms producing haploid gametes which fuse to form the zygote. Organisms included in this phylum have clearly evolved on at least three separate occasions. There are more than a million described species of animals, but the actual number may be closer to 10 million. Thus they may outnumber all other groups of organisms by a factor of perhaps 10 to 1."
