Hierarchical taxonomic systems: domain, kingdom, phylum, class, order, family, genus, species.

In lake st. clair there were huge areas where he found almost no mussels and others where he found ve different species and many individuals. Each species usually has morphological (physical) traits that can distinguish one species form another. At times the morphological traits of interest exist along a range of variation among conspeci cs (members of the same species) Sexual dimorphism: difference between male and female physical traits. Ontogeny changes are differences between immature and mature specimen, as development causes changes in morphology. Scienti c names can reveal important information about the species; e. g. zebra mussels=
