Crangonyx floridanus is a species of amphipod. Also known as the Florida crangonyx, Crangonyx floridanus is a small omnivorous, freshwater amphipod. These freshwater amphipods originated from North America. They have a high invasion potential due to their high growth rate and wide ecological amplitude. Their growth rates have a substantial effect on local populations of the natural communities. Native populations may be reduced or eliminated completely by this invading species.
