Habitat & Geographic Range

Tlaconete regordete

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

Range

Found in Mexico.

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.

Range

Distributed across Comoros, Indonesia, Mozambique, and South Africa. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Tlaconete regordete

The Chunky False Brook Salamander (Aquiloeurycea cephalica) is a Least Concern plethodontid salamander endemic to Mexico, found in cloud forest and humid montane habitats in the Sierra Madre Oriental and related mountain ranges. The genus Aquiloeurycea is a recently erected Mexican endemic genus segregated from the broader genus Pseudoeurycea, comprising several small, robustly built (hence 'chunky') salamanders associated with high-elevation forests. Like all plethodontids, A. cephalica is a lungless salamander that breathes entirely through its moist, vascularized skin and the lining of its mouth. It is a direct developer, skipping the aquatic larval stage entirely and laying eggs in terrestrial microhabitats such as rotting logs, leaf litter, and soil. A. cephalica inhabits cool, humid forests of pine-oak and cloud forest zones in northern Mexico, where it forages for small invertebrates in the leaf litter and soil. The IUCN assesses it as Least Concern due to its reasonably wide distribution within its montane range. Deforestation, cattle grazing, and the conversion of cloud forest to agriculture represent ongoing threats to populations throughout its range.

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.
