What defines the Class *Actinopterygii* according to the taxonomic summary table?
Answer
Ray-finned structure.
The summary table of *Danio rerio*'s taxonomy explicitly correlates the Class rank with the defining characteristic of a 'Ray-finned structure.' This refers to the specific skeletal support mechanism within the fins, where thin bony rays radiate outward, which is the distinguishing feature separating Actinopterygii from other fish classes. The status of being a 'Multicellular heterotroph' defines the Kingdom Animalia. The 'Presence of a notochord/nerve cord' defines the Phylum Chordata. 'Shared traits with carps and minnows' defines the Family Cyprinidae.
