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.

Urraca Verde

<em>Cissa chinensis</em>, commonly known as the common green magpie, is a passerine bird belonging to the genus Cissa within the family Corvidae. This species inhabits various aerial, terrestrial, and aquatic environments, with a documented range that includes Norway, suggesting occasional vagrant or introduced occurrences far outside its native Southeast and South Asian distribution. Common green magpie is assessed as Least Concern on the IUCN Red List. The species is typically associated with dense tropical and subtropical forests across its native range, where its brilliant green plumage, often fading to turquoise with age and sun exposure, renders it a striking forest bird. It is an omnivore typically foraging at mid and lower forest levels. Biological traits of this species remain poorly documented in the scientific literature.
