Panaque cochliodon, commonly known as the Blue-eyed Pleco, is a freshwater fish native to Colombia's Magdalena River basin. Notable for its striking blue eyes and robust body, it is a wood-eating catfish, using its specialized teeth to rasp on submerged wood. This behavior not only aids in digestion but also contributes to ecosystem maintenance by helping decompose wood debris in its habitat.

Panaque cochliodon, commonly known as the Blue-Eyed Pleco, is native to the Magdalena River basin located in Colombia, South America. This region is characterized by tropical and subtropical environments.

Panaque cochliodon typically inhabits freshwater river systems with moderate to fast-flowing water. The environmental conditions of these habitats include warm water temperatures, usually ranging from 24°C to 28°C (75°F to 82°F), and a pH level that tends to be neutral to slightly acidic. The water is often turbid, with a moderate to high level of dissolved oxygen.

The Blue-Eyed Pleco occupies an ecological niche as a detritivore and herbivore. It is adapted to feed on wood and plant matter, using specialized teeth to rasp off the surfaces of submerged wood. This dietary adaptation allows the species to play a role in the ecosystem as a decomposer, breaking down organic material and contributing to nutrient cycling within its habitat.
