Baleia jubarte

Entre as baleias grandes mais acrobáticas, as baleias-jubarte são famosas por seus cantos complexos e evocativos entoados pelos machos durante a temporada reprodutiva, podendo durar horas e evoluir ao longo do tempo. Atingindo 16 metros e 30 toneladas, realizam as migrações mais longas de qualquer mamífero. Encontradas em todos os oceanos, alimentam-se de krill e peixes pequenos usando a técnica cooperativa de rede de bolhas.

Chrysochromulina bergenensis is a unicellular marine haptophyte named after Bergen, Norway, near where it was first described, reflecting the strong tradition of phycological research centered on the Norwegian coast. It belongs to the genus Chrysochromulina, family Chrysochromulinaceae, class Prymnesiophyceae — a group of golden-brown microalgae distinguished by possession of a haptonema alongside two flagella. The haptonema is a flagella-like appendage unique to haptophytes that functions in prey capture and temporary substrate attachment. C. bergenensis is a nanoplankton species inhabiting coastal marine and occasionally brackish waters, and has been documented from Norwegian and Swedish coastal regions as well as from South American waters including Brazil, indicating a broader distribution than its type locality might suggest. In oligotrophic to mesotrophic marine environments, Chrysochromulina species including C. bergenensis contribute to picoeukaryotic and nanoeukaryotic primary production. The cell surface is ornamented with siliceous or organic scales whose morphology is species-diagnostic. Mixotrophy — the ability to both photosynthesize and ingest particulate food — is common across the genus and likely occurs in this species. C. bergenensis has not been assessed under IUCN Red List criteria and is classified as Not Evaluated. In ecological terms, haptophytes occupy key roles in oceanic carbon export, nutrient cycling, and as prey items for heterotrophic protists and copepods in temperate and boreal Atlantic food webs.
