Habitat & Geographic Range

Guitarra

Habitat

Native to South America, inhabiting ecosystems characteristic of the region.

Range

Found in Venezuela. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Lobo gris

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, deserts and xeric shrublands, and tropical and subtropical dry broadleaf forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Seychelles), Asia (Japan), Europe (5 countries), North America (7 countries), Oceania and the Pacific (Marshall Islands, Vanuatu), and South America (5 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Guitarra

The Chola Guitarfish (Pseudobatos percellens), also called the Southern Guitarfish, is a cartilaginous fish in the family Rhinobatidae (guitarfishes), characterised by a body plan intermediate between sharks and rays — with a flattened, ray-like disc at the front merging into a thick, shark-like tail. The species occurs in shallow coastal waters of the tropical western Atlantic from Venezuela south through Brazil, inhabiting sandy and muddy bottoms in estuaries, bays, and nearshore coastal habitats at depths generally less than 100 metres. Guitarfishes are benthic feeders, using their broad, flat rostrum to excavate sediment and uncover crustaceans, molluscs, and small fish. Like all elasmobranchs, they are ovoviviparous or viviparous, producing small litters of live pups. The IUCN classifies the Chola Guitarfish as Endangered, reflecting severe population declines caused by high levels of bycatch in trawl fisheries throughout its coastal range in Venezuela, Trinidad, and Brazil, combined with direct fishing for meat and fins. Guitarfishes globally are among the most threatened groups of marine vertebrates, with shallow coastal habitats intensively fished and offering little refuge from demersal fishing gear. Without significant reductions in fishing pressure and targeted management measures, continued decline is anticipated.

Lobo gris

El lobo gris (Canis lupus), el cánido silvestre más ampliamente distribuido, se extiende desde América del Norte a través de Eurasia en hábitats diversos que incluyen la tundra, bosques y praderas. Son animales altamente sociales que viven en manadas familiares lideradas por una pareja reproductora dominante. Como depredadores clave, los lobos regulan las poblaciones de presas y moldean profundamente la estructura del ecosistema, como demostró su reintroducción en Yellowstone. Antes muy perseguidos, las poblaciones se están recuperando en muchas regiones.
