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.

Bulbul Collarejo

<em>Spizixos semitorques</em>, the Collared Finchbill, is a bulbul in the family Pycnonotidae. This species is assessed as Least Concern on the IUCN Red List. It is native to eastern Asia, with its range including southeastern China, Taiwan, and adjacent areas. The Collared Finchbill inhabits forest edges, scrub, and bamboo thickets, and is typically found at middle to higher elevations. Members of the genus <em>Spizixos</em> are characterized by their thick, finch-like bills, which are adapted for feeding on hard-coated seeds and berries in addition to insects. The common name reflects both the collar-like markings on the plumage and the distinctive bill morphology. Diet, population estimates, population trend, and biological measurements including average length, weight, and lifespan are not specified in available records. Biological traits of this species remain poorly documented in the scientific literature. The species is associated with aerial, terrestrial, and aquatic environments within its range. Its Least Concern status indicates stable populations across its eastern Asian range.
