What is contained within the dorsal fin structure of the Yellow Bullhead?

Answer

One strong, serrated spine followed by soft rays and an adipose fin.

The dorsal fin, located atop the back of the fish, exhibits characteristics typical of its family. It is relatively small in appearance compared to some other catfish but contains crucial structural elements. Specifically, it features one spine that is both strong and possesses serrations along its edge. Following this spine are several soft rays that complete the fin structure. Furthermore, a feature characteristic of the entire Ictaluridae family, the Yellow Bullhead possesses a small, fleshy adipose fin situated posteriorly on the back, positioned between the dorsal fin and the caudal fin.
