Habitat & Geographic Range
Colares stingray
Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 6 distinct biome types within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.
Found in Venezuela. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.
Epaulard
Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.
Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador, Venezuela).
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.
