What type of fish is included in the sunfish category?

The sunfish category includes various species that are primarily characterized by their distinctive body shape, large size, and vibrant colors. The pumpkinseed is a notable representative of the sunfish family, which is known for its round body, spiny dorsal fin, and brightly colored markings.

While the bass is also a popular freshwater fish species and belongs to the sunfish family (Centrarchidae), it is often categorized separately due to its size and angling characteristics. Catfish, on the other hand, belong to an entirely different family (Ictaluridae) and are not included in the sunfish category at all.

Therefore, the correct answer focuses specifically on the pumpkinseed as it is a direct example of a fish classified within the sunfish category, while the others do not fit into this group.
