Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Coast Indigo

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Found in Cuba.

blue whale

O maior animal que já viveu na Terra, as baleias-azuis podem atingir 33 metros e 200 toneladas — seus corações sozinhos pesam tanto quanto um carro pequeno. Encontradas em todos os oceanos, migram entre áreas de alimentação polares e áreas de reprodução tropicais. Filtradores que consomem até 4 toneladas de krill diariamente. Em perigo, com populações globais estimadas em 10.000–25.000 após a quase extinção causada pela caça baleeira no século XX.

Coast Indigo

Coast indigo (Indigofera miniata) is a perennial herb or subshrub in the family Fabaceae, native to the coastal scrub, pine barrens, and sandy grasslands of Cuba and the broader Caribbean region. Like other members of the genus Indigofera, it produces compound pinnate leaves and racemes of small, pea-type flowers, though in this species the flowers are notably small and pinkish to reddish. The genus Indigofera is best known for Indigofera tinctoria, the source of natural indigo dye, but most species including Indigofera miniata have not been commercially exploited for dye production. Coast indigo grows in open, sunny, often disturbed habitats including sandy coastal plains, roadsides, and degraded scrubland, benefiting from its ability to fix atmospheric nitrogen through root nodule bacteria—a common trait in the legume family. The IUCN assesses it as Least Concern, reflecting its ability to persist in disturbed and marginal coastal habitats across the Caribbean. Regional populations are affected by coastal development and vegetation clearance but are not considered globally threatened.
