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.

common fringe-rush

<em>Fimbristylis dichotoma</em>, commonly known as the common fringe-rush, is a sedge-like plant in the family Cyperaceae. It has a cosmopolitan distribution, occurring across Africa, Asia, Europe, North America, Oceania, and South America, making it one of the more broadly distributed species in its genus. The species typically inhabits a variety of open, disturbed, and wetland environments, including rice paddies, roadsides, stream margins, and grasslands. <em>Fimbristylis dichotoma</em> is an annual or perennial herb that typically forms tufted clumps and produces characteristic umbel-like inflorescences. It is assessed as Least Concern, consistent with its wide global distribution and adaptability to a range of habitat types. The species plays a role in colonizing disturbed soils and contributing to ground cover in open habitats. Biological traits of this species remain poorly documented in the scientific literature. Its tolerance of varied environmental conditions, including seasonal flooding and drought, contributes to its success across multiple continents and diverse ecological settings.
