Taxonomical method used to classify species of organisms into clades, each of which contains an ancestor organism and all its descendants, based on synapomorphies (shared derived characters). Cladistic classifications are usually presented in the form of a cladogram.

Order of small, aquatic crustaceans commonly referred to as 'water fleas'.

Branching, tree-like diagram used in cladistics to represent the evolutionary tree of life. Used to depict phylogenetic relationships and show points at which species diverged from their common ancestral forms.

In taxonomy, the arrangement of organisms into taxonomic groups according to their degree of evolutionary relatedness.

A Weberian ossicle.

Club-shaped.

Refers to the collar bone in human anatomy. Present in the pectoral girdle of some fishes as a paired, dermal bone ventral to or fused with the cleithrum.
