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 mantoniae is a marine haptophyte alga named in honor of the pioneering British phycologist Irene Manton, whose electron microscopic studies of algal flagella and scales transformed the taxonomy of nanoplankton in the mid-twentieth century. The species belongs to the family Prymnesiaceae and displays the characteristic Chrysochromulina body plan: two heterodynamic flagella, a haptonema of variable length, and a cell surface coated with organic scales. C. mantoniae inhabits coastal marine waters of the North Atlantic, consistent with the geographic range of most formally described Chrysochromulina species. As a planktonic photosynthesizer and potential mixotroph, it contributes to the cycling of carbon and nutrients in the marine microbial food web. The haptonema's role in cell adhesion and prey capture has been studied extensively in closely related species, revealing complex behaviors including coiling and extension dynamics. The IUCN has not evaluated the conservation status of C. mantoniae, classifying it as Not Evaluated. This reflects the general absence of threat assessment methodology for free-living marine microorganisms whose populations are shaped largely by oceanographic rather than anthropogenic drivers.
