The document discusses the classification of animals into vertebrates and invertebrates. Vertebrates are animals with backbones and include mammals, birds, fish, reptiles and amphibians. Invertebrates lack backbones and include worms, shellfish and microorganisms. The document then provides more details about the characteristics of different vertebrate groups like mammals giving birth to live young and fish living their whole lives in water.
