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.

Cocha Chirping Frog

The cocha chirping frog (Adenomera andreae) is a small terrestrial frog belonging to the family Leptodactylidae, widely distributed across lowland and submontane forest of northern South America, including Venezuela, Trinidad, Guyana, Suriname, French Guiana, and parts of Brazil and Colombia. It inhabits leaf litter, stream margins, and forest floor habitats in humid tropical and gallery forests, where its cryptic brown coloration provides effective camouflage against predators. Like other members of the genus Adenomera, this species practices direct development: eggs are deposited in foam nests on moist land rather than in open water, and juveniles hatch as fully formed froglets, bypassing the free-living tadpole stage entirely. Males produce a distinctive chirping advertisement call, often from concealed positions among roots or leaf debris, to attract females during breeding seasons that may extend throughout much of the year in equatorial localities. The cocha chirping frog is classified as Least Concern by the IUCN, reflecting its broad distribution, presumed large populations, and tolerance for moderately disturbed habitats including secondary forest and forest edges. It can persist in areas subject to low-intensity logging and is frequently encountered in wildlife surveys across its range. Primary threats are large-scale deforestation and drainage of wetland habitats, though these pressures have not yet driven significant population decline across its wide geographic range.
