Colares stingray

<em>Fontitrygon colarensis</em>, known as the Colares Stingray, is a ray in the family Dasyatidae. This species is classified as Critically Endangered on the IUCN Red List, indicating a very high risk of extinction in the wild. It is recorded in Venezuela and is associated with a diverse range of habitats including tropical and subtropical moist and dry broadleaf forests, grasslands, and at least six distinct biome types, suggesting it may occupy freshwater or coastal environments where such biomes interface. The genus <em>Fontitrygon</em> comprises freshwater and brackish-water stingrays found in South America and West Africa. Diet information for <em>Fontitrygon colarensis</em> is not available in provided records. Biological traits including body length, weight, and lifespan have not been documented for this species in available sources. Biological traits of this species remain poorly documented in the scientific literature. The Critically Endangered status of this ray underscores the urgency of conservation efforts and further scientific study to understand its biology, population size, and the threats driving its decline.
