Species Profile
Ciego (Cetopsis motatanensis) is a small, translucent catfish endemic to the Orinoco River basin in Venezuela. This pale, eyeless species exhibits typical cave-adapted characteristics with reduced pigmentation and sensory adaptations for life in dark aquatic environments. As a specialized predator, it plays a crucial role in the nutrient cycling of its restricted freshwater ecosystem.
Cetopsis motatanensis faces severe threats from habitat degradation due to deforestation, agricultural expansion, and water pollution in its limited range within the Lake Maracaibo basin. The species' restricted distribution makes it particularly vulnerable to localized environmental changes and human activities that alter water quality and flow patterns.
Key Facts
Habitat & Distribution
