Sexual dimorphism

Neoplecostomus sapucai males have shorter and robust teeth, while females have more slender teeth.

Neoplecostomus sapucai live in stony, shallow streams that have crystal clear water and rapid flow. The species was found living near manmade things like highways or pastures, showing that humans don't pose that much of a threat on the species. The species is found in 16 different sites within the Sapucaí River drainage.

The researchers who found Neoplecostomus sapucai said they named it after the Sapucaí River, where the species was found.
