Phallotorynus fasciolatus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Phallotorynus fasciolatus faces severe population decline due to extensive habitat destruction from urban expansion and agricultural conversion in its restricted range. Water pollution from industrial runoff and domestic sewage has degraded the pristine freshwater systems this species requires for reproduction. The introduction of non-native fish species has created additional competitive pressure and predation risks in its already limited habitat.
Habitat
This small freshwater fish inhabits clear, slow-flowing streams and shallow pools in coastal lowland areas of southeastern Brazil. It requires well-oxygenated waters with dense aquatic vegetation and sandy or muddy substrates for feeding and breeding.
