Synodontis guttatus

Synodontis guttatus, commonly known as the spotted squeaker or spotted upside-down catfish, is a freshwater catfish species endemic to the Congo River basin in Central Africa. This distinctive fish belongs to the family Mochokidae and is characterized by its spotted pattern and ability to swim inverted, feeding from the water surface. The species inhabits riverine environments within the Congo basin, where it plays an ecological role as both predator and prey in the aquatic food web.

Currently classified as Critically Endangered by the IUCN, S. guttatus faces severe population pressures, though the exact population trend remains unknown due to limited monitoring data. The primary threats to this species include habitat degradation from deforestation, agricultural expansion, and human settlement along riverbanks, which increases sedimentation and pollution in waterways.

Overfishing and the use of destructive fishing practices in the Congo River system further compound these pressures. Climate change may also affect water levels and temperature regimes critical to the species' survival. The remote and politically unstable nature of much of the Congo basin has hindered comprehensive conservation efforts and population assessments.

Limited research infrastructure and ongoing conflicts in the region make it difficult to implement effective monitoring programs or habitat protection measures. Conservation initiatives would benefit from international cooperation, local community engagement, and improved governance of freshwater resources throughout the Congo River basin.

This species inhabits freshwater riverine environments within the Congo River basin in Central Africa. It occupies various river habitats where it can utilize its unique inverted swimming behavior to feed from surface waters.
