Tsingisoolense

Tsingisoolense is a rare and critically endangered species of freshwater fish belonging to the genus *Tsingy* within the family Cyprinidae. This species is endemic to the Tsingy de Bemaraha National Park in southwestern Madagascar, where it inhabits the clear, fast-flowing streams and rivers of the region’s unique limestone karst landscape. The name "tsingisoolense" derives from the local Malagasy term *tsingy*, referring to the jagged limestone formations, and the Latin suffix *-ense*, indicating its place of origin.

The tsingisoolense is characterized by its slender, elongated body, typically reaching lengths of around 10 centimeters. Its coloration is predominantly silver-gray with faint vertical stripes, which may help it blend into its rocky habitat. Like many cyprinids, it is an omnivorous species, feeding on small invertebrates, algae, and detritus. Its ecological role within the ecosystem is likely significant, contributing to nutrient cycling and serving as prey for larger predators.

Due to its restricted range and the fragility of its habitat, the tsingisoolense is classified as Endangered by the International Union for Conservation of Nature (IUCN). Threats to its survival include habitat degradation from deforestation, pollution, and the construction of dams, which alter water flow and sediment dynamics. Additionally, invasive species and overfishing in the region pose further risks to its population.

Conservation efforts for the tsingisoolense are limited but include habitat protection within the Tsingy de Bemaraha National Park, a UNESCO World Heritage Site. Research on its biology and population dynamics is ongoing, with efforts to raise awareness among local communities about sustainable fishing practices. Genetic studies may also help inform conservation strategies by assessing genetic diversity and connectivity among populations.
