Habitat & Geographic Range

Yetapá Chico

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

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

Celacanto

Habitat

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 8 distinct biome types spanning the Australasia and Afrotropic and Indomalayan realms. Populations are also found in montane and highland environments at higher elevations.

Yetapá Chico

The cock-tailed tyrant (Alectrurus tricolor) is a striking and unusual flycatcher in the family Tyrannidae, named for the remarkable elongated, spatula-shaped outer tail feathers of the male, which can exceed the body length and are displayed during aerial courtship flights over open grasslands. The species inhabits wet and seasonally flooded grasslands, cerrado savanna, and campos in the interior of South America, including central Brazil, eastern Bolivia, Paraguay, and northeastern Argentina — not Norway, as erroneous database entries suggest. Males combine conspicuous black, white, and rufous plumage with their extraordinary tail streamers in an elaborate display to attract females on leks; females are cryptically streaked brown. The cock-tailed tyrant is a ground- and low-vegetation forager, preying on insects and other small invertebrates gleaned from grass stems and caught in aerial sallies. The species is classified as Vulnerable by the IUCN due to extensive and continuing conversion and degradation of its native Neotropical grassland habitat through intensive soy and sugarcane agriculture, cattle ranching, fire management changes, and drainage of seasonally flooded grasslands. Populations have declined significantly across much of its range, particularly in Brazil and Paraguay. The species is a flagship for threatened grassland conservation in South America, where relatively little protection has historically been directed at open-country habitats compared to forest ecosystems.

Celacanto

Un fósil viviente considerado extinto durante 65 millones de años hasta su redescubrimiento frente a Sudáfrica en 1938, los celacantos pueden alcanzar 2 metros y 90 kg. Pertenecen a un antiguo linaje de aletas lobuladas más relacionado con los tetrápodos que con los peces de aletas radiales, lo que los hace científicamente invaluables para comprender la evolución de los vertebrados. Encontrados en hábitats de arrecifes rocosos profundos del Océano Índico, son nocturnos y experimentan fertilización interna, dando a luz crías completamente formadas. En Peligro Crítico.
