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 limonia is a species of marine haptophyte microalga in the genus Chrysochromulina, family Chrysochromulinaceae, class Prymnesiophyceae. The specific epithet limonia, derived from Latin for lemon-yellow, likely references the characteristic golden-yellow coloration of the cells or a particular pigmentation pattern observable under light microscopy. Chrysochromulina species are golden-brown algae whose color arises from the combination of chlorophylls a and c with fucoxanthin and other carotenoid pigments within their chloroplasts. C. limonia has been recorded from Norwegian and Swedish coastal marine waters, contributing to the substantial representation of this genus in northern European phycological collections and literature. Norwegian fjords and coastal shelf habitats provide cold, seasonally productive conditions where Chrysochromulina species frequently constitute a significant fraction of the nanoplankton community. Like its congeners, C. limonia is a small, free-living pelagic organism that engages in photosynthesis and potentially mixotrophy, and it bears the characteristic haptonema structure alongside two flagella. Cell surface scales, whose morphology is visible under electron microscopy, provide the primary characters for distinguishing C. limonia from other species in the genus. The haptonema, when extended, can exceed the cell body in length and assists in temporary attachment or prey capture. C. limonia has not been evaluated under IUCN criteria and carries a conservation status of Not Evaluated. It represents one component of the rich haptophyte diversity that characterizes Scandinavian coastal marine microflora.
