Muscle tissue contracts to cause all types of body movement from locomotion of the organism to movements within the body itself. Nervous tissue contains neurons, or nerve cells, which transmit nerve impulses. There are four main types of animal tissues: nervous, muscle, connective, and epithelial. A tissue is a collection of similar cells that had a common embryonic origin. All animals are eukaryotic, multicellular organisms, and almost all animals have specialized tissues. Invertebrates include a huge diversity of animals, millions of species in about 32 phyla, which we can just begin to touch on here.Įven though members of the animal kingdom are incredibly diverse, animals share common features that distinguish them from organisms in other kingdoms. Although in general we are most familiar with vertebrate animals, the vast majority of animal species, about 95 percent, are invertebrates. The kingdom of animals is informally divided into invertebrate animals, those without a cranium, and vertebrate animals, those with a cranium.
