Which Class groups the White Crappie, characterized by bony spines or rays supporting its fins?
Answer
Actinopterygii
The Class placement for *Pomoxis annularis* is Actinopterygii. This group represents the ray-finned fishes and constitutes the most numerous class within the entire vertebrate lineage. The defining anatomical feature of this class, as implied by the name Actinopterygii, is the structural support provided to their fins by bony spines or rays. This contrasts significantly with the Class Sarcopterygii (lobe-finned fishes), which possess fleshy, lobe-like fins and includes more distantly related lineages such as tetrapods and lungfish.
