Rhinelepis aspera is a large armored catfish with very rough and spiny armor. It lives on the bottom of freshwater rivers in Brazil and helps clean the water from algae.
Rhinelepis aspera is distinguished by its very rough spiny armor that protects it from predators in fast rivers. It is important for nature because it cleans the bottom of excess algae and debris.
Scrapes food with its suction-cup mouth.
Immature form that undergoes metamorphosis before adulthood.
