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.

Junco de Rana

<em>Juncus bufonius</em>, commonly called toad rush, is a small annual rush in the family Juncaceae with a near-cosmopolitan distribution, occurring on every continent except Antarctica. It is found throughout Europe, Asia, Africa, the Americas, and Australia, thriving in a wide diversity of habitats including muddy pond margins, seasonal wetlands, trampled pathways, agricultural fields, and disturbed moist ground. The species typically grows in low-lying areas that experience seasonal flooding or waterlogging, tolerating a range of soil types from sandy to clay-rich. <em>Juncus bufonius</em> is a diminutive plant, typically reaching 5 to 35 centimeters in height, with slender, wiry stems and inconspicuous greenish flowers arranged in loose, branched inflorescences. As an annual, it completes its life cycle rapidly, producing abundant small seeds that persist in the soil seed bank and facilitate colonization of newly disturbed wet habitats. The species plays an ecological role as an early colonizer of open, moist ground and provides microhabitat and food resources for small invertebrates. It is currently assessed as Least Concern by the IUCN, with a stable and widespread global population. Biological traits such as average lifespan duration beyond a single season, body length measurements, and weight remain poorly documented in the scientific literature.
