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.

Collins' rockcress

<em>Boechera collinsii</em>, commonly known as Collins' rockcress, is a plant species belonging to the genus <em>Boechera</em> within the family Brassicaceae, which includes mustards and related flowering plants. This species has been documented in Canada, where it inhabits diverse terrestrial environments. Members of the genus <em>Boechera</em> are typically herbaceous perennials or biennials adapted to rocky outcrops, cliff faces, talus slopes, and open woodland habitats, often tolerating thin, well-drained soils where competition from other vegetation is limited. The species has not been formally assessed for conservation status by major evaluation bodies. As a flowering plant, <em>Boechera collinsii</em> does not engage in dietary behavior in the traditional sense; it produces energy through photosynthesis and may support pollinators and herbivores as part of its native ecosystem. Biological traits of this species remain poorly documented in the scientific literature. Further botanical surveys in Canadian habitats are needed to clarify the distribution, population status, and ecological interactions of <em>Boechera collinsii</em>.
