blue whale

O maior animal que já viveu na Terra, as baleias-azuis podem atingir 33 metros e 200 toneladas — seus corações sozinhos pesam tanto quanto um carro pequeno. Encontradas em todos os oceanos, migram entre áreas de alimentação polares e áreas de reprodução tropicais. Filtradores que consomem até 4 toneladas de krill diariamente. Em perigo, com populações globais estimadas em 10.000–25.000 após a quase extinção causada pela caça baleeira no século XX.

Chrysochromulina campanulifera is a marine haptophyte microalga belonging to the genus Chrysochromulina within the family Chrysochromulinaceae, class Prymnesiophyceae. The species epithet campanulifera, meaning bell-bearing, references a distinctive morphological feature of the cell — likely a bell-shaped scale or structural component visible under electron microscopy. This feature exemplifies how fine-scale ultrastructural characters drive species discrimination within Chrysochromulina, a genus currently containing more than fifty described species. C. campanulifera inhabits coastal marine waters and has been documented from Norwegian and Swedish coastal regions, environments that have yielded a disproportionate number of haptophyte species descriptions due to focused Scandinavian phycological research programs from the 1950s onward. The species is a nanoplankton organism — typically two to twenty micrometers in diameter — that participates in primary production and marine carbon cycling. Like other haptophytes, it possesses chloroplasts containing chlorophylls a and c along with carotenoid accessory pigments that give the cells their characteristic golden-brown coloration. The coiling haptonema, a defining feature of the genus, distinguishes Chrysochromulina from related genera such as Prymnesium and Phaeocystis. C. campanulifera has not been formally assessed under IUCN criteria and retains a conservation status of Not Evaluated. Research on this and related species informs understanding of nanoplankton diversity, marine biogeography, and the ecological dynamics of temperate and boreal coastal oceans.
