Organism that: – is eukaryotic – is multicellular – is heterotrophic (consumer) – lacks cell walls – is motile in some stage of its life cycle – usually undergoes embryonic development (blastula stage) – is usually capable of sexual reproduction  What is an Invertebrate? Animal without a vertebral column All animal phyla except Chordata consist entirely of invertebrates Invertebrates More than 95% of animal species are invertebrates Most of these are insects Proportion of described species  Invertebrate Diversity We will cover the classification and systems of the following animal groups: Porifera Cnideria Platyhelminthes Nematoda Annelida Mollusca Arthropoda Echinodermata Animal Diversity Animals first arose 540 MYA Evolution over time into the diversity of forms we see today Phylogenetic tree (“tree of life”)  Why Study Animal Diversity? Reconstruct phylogeny of animal life Know when major evolutionary transitions took place Understand the processes that generate and maintain species diversity Forms the basis for all other scientific study of animals
