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.

Dúcula moluqueña

The cinnamon-bellied imperial pigeon (Ducula basilica) is a large, arboreal fruit pigeon in the family Columbidae, endemic to the Moluccas (Maluku Islands) of eastern Indonesia, including Halmahera, Bacan, Obi, Ternate, and adjacent smaller islands. It inhabits primary and mature secondary lowland and hill forest, where it feeds on fruits, figs, and berries in the forest canopy. The plumage is largely dark metallic green above with a distinctive cinnamon-rufous underside that differentiates it from related imperial pigeons. Large fruit pigeons of the genus Ducula are important seed dispersers in island forest ecosystems, capable of swallowing large fruits whole and dispersing seeds far from parent trees. The species is classified as Least Concern by the IUCN, with populations considered stable in the Moluccas. However, all large fruit pigeons are susceptible to hunting pressure and habitat loss, and monitoring is needed given ongoing forest conversion in eastern Indonesia. The Moluccas harbor exceptional bird diversity due to their position between Asian and Australasian biotas. This species is absent from Europe entirely; Norwegian database records are incorrect geographic artifacts. Conservation of intact lowland forest in the Moluccas is important for this and many co-occurring endemic species.
