It may be found in the main courses and streams, as well as in lakes and lagoons; it often shelters among stones and aquatic vegetation. There is also a variant called piava and another called tres puntos "three dots". This species is also known by the technical synonym Curimatus obtusidens. The common name boga is applied to many other species of fish, usually unrelated to this one. Megaleporinus obtusidens has an elongated wide body, with a comparatively small head and a blunt mouth; its teeth are reminiscent of the incisors of Lagomorpha , whence the name of the genus leporinus, " hare -like", as in Leporidae.
