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.

Chrysochromulina apheles is a marine haptophyte microalga in the genus Chrysochromulina, family Chrysochromulinaceae, class Prymnesiophyceae. Members of this genus are distinguished by their coiling haptonema, two flagella of approximately equal length, and a covering of organic scales on the cell surface — features used extensively in species identification through electron microscopy. C. apheles inhabits coastal marine environments and has been recorded from Norwegian and Swedish waters, regions where intensive phycological surveys during the late twentieth century yielded numerous new haptophyte species descriptions. These subarctic and temperate Atlantic coastal waters sustain diverse nanoplankton communities in which Chrysochromulina species are frequently abundant components. The epithet apheles derives from Greek, referencing a morphological characteristic of the cell or scale structure. As a phytoplankton organism, C. apheles participates in primary production, converting inorganic carbon to organic matter through photosynthesis, and may also engage in phagotrophy of bacterial cells. Some Chrysochromulina species produce polyunsaturated fatty acids and occasionally bioactive compounds. The taxon has not been evaluated under IUCN criteria and carries a conservation status of Not Evaluated, reflecting the general challenge of assessing extinction risk in free-living marine microalgae whose populations are cosmopolitan and difficult to census. Understanding the ecology and distribution of species like C. apheles contributes to knowledge of marine microbial diversity and the functioning of pelagic food webs in northern Atlantic ecosystems.
