Kingdom Animalia

Kingdom Animalia

Members of the animal kingdom are eukaryotic and multicellular but have no cell wall or photosynthetic pigments. They are mostly motile and they are heterotrophic, which means they must feed on other organisms and cannot make their own food. They reproduce sexually or asexually. Animals store carbon as glycogen and fat. Important examples of this kingdom include: Porifera (sponges), Cnidaria (jellyfish), Nematoda (nematode worms), Platyhelminthes (flatworms), Annelidas (segmented worms), Mollusca (Snails and Squid), Echinodermata (starfish), Arthropoda (Insects and Crustaceans), Chordata (includes all the vertebrates: fish, amphibians, reptiles, birds, mammals).

Classes of Vertebrates


Optional Activity: Investigate examples of life forms from each kingdom


To investigate examples from each kingdom.


  1. Research one beneficial and one harmful application of one member from each kingdom, with examples from their use. (Use as a research tool for your favourite animal or plant or for nice pictures of insects).
