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.

Cistícola de Njombé

The churring cisticola (Cisticola njombe) is a small insectivorous warbler in the family Cisticolidae, endemic to the highlands of East Africa. It inhabits montane grasslands, bracken-fern slopes, and the margins of high-altitude forest patches, primarily in the Nyika Plateau, the Njombe highlands of southern Tanzania, and adjacent areas of Malawi and Zambia. The species occupies elevations typically between 1,500 and 2,500 meters, where it forages low in dense grass and sedge clumps, gleaning insects and small invertebrates. The churring cisticola is named for its distinctive mechanical churring song, which males produce from low perches or during short display flights. It is a compact, streaked brown bird with a rufous-washed tail and pale underparts, closely resembling related montane cisticolas. The species is classified as Least Concern by the IUCN, with populations considered stable across its restricted highland range. Like other afromontane endemics, it depends on the persistence of intact highland grassland ecosystems, which face ongoing threats from agricultural encroachment, fire management changes, and human settlement. Taxonomic relationships within the Cisticola genus are complex, and the njombe cisticola has been subject to periodic revision. Conservation of afromontane grasslands in Tanzania and Malawi is critical for this and many co-occurring endemic species.
