Lesson plan
Bryconops
Bryconops is a genus of freshwater ray-finned fish in the family Iguanodectidae from South America. It consists of small fish, all under half-a-foot long, with slender bodies and silvery scales, though there is some mild color variation. Several species can be identified by way of a humeral patch (a mark near the pectoral fin), and others have a reddish ocellus, or eyespot, on one or both lobes of the dorsal fin. Many Bryconops prefer clearwater environments with a strong current, though some are partial to slow-moving blackwater, and several are endemic to their locale. The majority of species are from Brazil or Venezuela. Rivers and river basins that house species of Bryconops include the Tapajos, Orinoco, Tocantins, Negro, and Madeira. Few species of Bryconops have been evaluated as far as conservation status, but most of them are believed to be low-risk species. The greatest threats to population levels come almost entirely in the form of anthropogenic hazards, including mining, dam construction, farmland settlement, and destruction of the riparian zone. Nonetheless, several species are found in areas of protected forest, which decreases some of the survival pressure.
