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.
