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.

Búho nival

El buho niveo (Bubo scandiacus) esta clasificado como En Peligro Critico (CR) en la Lista Roja de la UICN. Enfrenta un riesgo extremadamente alto de extincion en estado silvestre debido a una severa disminucion poblacional y la perdida de habitat.
