Document Summary

Animal- members of the kingdom animalia; eukaryotic, multicellular, heterotrophic (that is, they cannot produce their own food) organisms. Many of these organisms have body parts specialized for different activities and can move during some stage of their lives. Animals are organisms that share three characteristics: all of them eat other organisms, all can move during at least one stage of their development, and all are multicellular. These organisms (such as humans, cows, and scorpions) have left and right sides that are mirror images. and sea anemones. During gut development, does the mouth or anus form first: protostomes (mouth first, deuterostomes (mouth second) Sponges are animals that lack tissues and organs (11. 4) Sponges are among the simplest of the animal lineages. A sponge consists of a hollow tube with pores in its walls; it has no tissues or organs. Sponges reproduce sexually (by producing egg and sperm) and asexually (by budding)
