A selfish swimming in a large lake.

Selfish is a freshwater fish of the family Gadidae, very closely related to the saltwater cod. Unlike cod, selfish are not widely consumed due to their meat's bitter taste, hence their names. Selfish are native to much of North America's lakes and rivers, but has since spread into man-made waterways due to their adaptations to survive and flourish in human settlements. They are omnivores that mainly feed on algae, insects, smaller fish, frogs, carrion, and sometimes eggs (fish and amphibian eggs) ,small reptiles, small birds, and small mammals, so they are also known as river crows due to their wide range of food sources. They are able to tolerate well with pollution and invasive species like carp, so they are not threatened to extinction.
