Faxonius

Faxonius is a genus of freshwater fish belonging to the family Cyprinidae, commonly known as minnows and carps. This genus is native to North America and includes several species that were previously classified under the genus Notropis. The revision that established Faxonius recognized distinct evolutionary lineages and morphological characteristics.

Species within Faxonius are generally small to medium-sized fish, often found in clear, flowing waters of streams and rivers. They exhibit a variety of color patterns, which can differ between species and even within populations depending on geographic location and environmental conditions. Their diet typically consists of invertebrates, algae, and plant matter.

Key distinguishing features of Faxonius include their pharyngeal teeth, which are arranged in a specific pattern, and their overall body shape. They are an important part of the aquatic ecosystem, serving as prey for larger fish and contributing to nutrient cycling. Conservation status varies among Faxonius species, with some being abundant while others face threats from habitat degradation and pollution. The genus is named in honor of Blake Faxon, a notable ichthyologist.
