Etheostoma nianguae (Niangua Darter) is a species of ray-finned fishes in the family Percidae. They are listed as vulnerable by IUCN. They are associated with freshwater habitat. Individuals can grow to 13.0 cm. They have sexual reproduction.

URI: http://eol.org/schema/terms/vulnerable
Definition: A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable, and it is therefore considered to be facing a high risk of extinction in the wild.

oceanic benthopelagic zone
- URI: http://purl.obolibrary.org/obo/ENVO_01000040
- Definition: The benthopelagic zone biome comprises regions of the marine water column which usually coincide with the benthic boundary layer (BBL) - the layer of isothermal and isohaline water contiguous to the sea floor. A general reversal in the declining gradient of pelagic biomass may be observed here, perhaps explained by viable nutrition on the sea floor being resuspended by bottom currents. This zone typically extends 100 m above the seafloor, but may reach upto1000 m during benthic storms.

lens eyes
- URI: https://eol.org/schema/terms/lens_eyes
- Definition: Relative to pinhole eyes, lens eyes have greatly improved resolution and image brightness. The lens converges incoming rays of light, thereby reducing the angle over which each photoreceptor receives light, and forming an image focused on the retina. Most lens eyes have "accommodation"; they can focus an image either by physically moving the lens toward or away from the retina or by using eye muscles to adjust the shape of the lens.
