Ballena azul

El animal más grande que se conoce haya vivido en la Tierra; las ballenas azules pueden alcanzar 33 metros y 200 toneladas — sus corazones solos pesan tanto como un automóvil pequeño. Se encuentran en todos los océanos y migran entre las zonas de alimentación polares y las áreas de reproducción tropicales. Son filtradoras que consumen hasta 4 toneladas de kril al día. En peligro de extinción, con poblaciones globales estimadas entre 10.000 y 25.000 tras casi extinguirse por la caza de ballenas en el siglo XX.

Rana de Cristal de Coloma

<em>Nymphargus colomai</em>, commonly known as Coloma's Glassfrog, is an amphibian species belonging to the genus <em>Nymphargus</em> within the family Centrolenidae. Glassfrogs are named for their translucent ventral skin, through which internal organs are visible, a trait characteristic of this family. This species is classified as Endangered, indicating a high risk of extinction if current conditions and threats persist within its range. It inhabits freshwater-associated environments, moist forests, and wetland habitats typical of neotropical regions, where glassfrogs are typically found on vegetation near fast-flowing streams. Specific country-level distributional records are not detailed in current documentation. The reproductive biology of glassfrogs involves egg deposition on vegetation overhanging water, with hatching tadpoles dropping into streams below. Dietary information specific to this species has not been documented, though centrolenid frogs generally consume small invertebrates. Biological traits of this species remain poorly documented in the scientific literature. Threats facing <em>Nymphargus colomai</em> include deforestation, stream degradation, and the chytrid fungal disease affecting amphibians globally.
