The 5 Key Differences Between Bluegill and Sunfish
The Bluegill and Sunfish, despite their similarities, have some key differences that set them apart. These species’ differences impact their interaction with their environment and other species. Here is a closer look at these differences:
1. Limited or Broad Range
The Bluegill is a freshwater species native to North America. Sunfish, however, are saltwater fish who reside in tropical and temperate areas of the Atlantic and the Pacific Oceans. The Bluegill may inhabit rivers, streams, or ponds as a freshwater species.
2. Bluegills Are Flatter, Sunfish May Mimic Sharks
The Bluegill has a flat, slender body, while the Sunfish has a longer body. Although Bluegills have dorsal and pectoral fins, Sunfish have protruding dorsals that often cause people to mistake them for sharks. Another feature unique to the Sunfish and its ocean environment is countershading, which allows the fish to take on other colors to disguise it from predators.
3. Different Colors for Different Habitats
These panfish species boast different types of colors. For example, the Bluegill has a dark blue body, with black spots on the dorsal fins and yellow bellies. On the other hand, Sunfish have shades that include brown, silver-grey, and white, with the color variation being one of the facts that highlight the differences the most.
4. Much Different Sizes!
One of the easiest ways to make identification between the two species is the significantly different size. The Bluegill is a uniform size of about 12 inches long, regardless of whether living in a river or pond setting. Sunfish are a larger species, averaging between 5 feet, 11 inches long to 10 feet long.
5. Two Different Diets
These panfish species have different diets because of their habitats. One of the essential facts about the dietary habits of these fish is that the Bluegill only eats plankton. On the other hand, Sunfish have a diet that includes fish and fish larvae and squid and crabs.
