Résumé
We collected fifty specimens of the colubrid water snake Afronatrix anoscopus during a single day in a 100 m section of a rainforest stream of southeastern Guinea. Food items were present in the digestive tracts of 17 specimens, with a significantly higher occurrence in females (48%) than in males (14%). Small fishes (<2 g) belonging to four species (Tilapia brevimanus,Epiplatys hildegardae, Barbus sacratus, and Kribia kribensis) were the main prey, representing 89% of the total numbers of prey items. A anuscopus is probably one of the main predators of juvenile fishes in the West African rainforest.
