perruno catfish
Perruno Catfish are eager bottom feeders. They scavenge the murky river bottoms of Venezuela, particularly in the Rio Negro and Lake Maracaibo basin. Catfish use “whiskers” - known as barbels - to navigate through their low light environments. The barbels contain both taste buds and olfactory sensors allowing Perruno catfish to taste and smell their environment in search for food.
