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.

Coelosphaerium confertum is a colonial planktonic cyanobacterium in the family Merismopediaceae, distinguished from related species by the relatively compact arrangement of cells within its gelatinous colonial matrix. Like other Coelosphaerium species, it forms roughly spherical mucilaginous colonies in which cells are positioned near the colony periphery. The genus belongs to the order Chroococcales and is characteristic of temperate freshwater habitats including lakes, ponds, and slow-moving rivers with moderate to high nutrient levels. Coelosphaerium confertum has been recorded from freshwater bodies in Denmark and other northern European countries, where it occurs as part of the phytoplankton assemblage during summer and early autumn months when temperatures are sufficient to sustain its growth. Cyanobacteria of this type are primary producers that fix atmospheric carbon and contribute to the base of aquatic food webs, supporting zooplankton and higher trophic levels. Under conditions of elevated phosphorus and nitrogen from agricultural runoff and wastewater, bloom-forming cyanobacteria can proliferate and alter the ecological character of water bodies. While Coelosphaerium confertum is not typically identified as a toxic bloom-former, its ecological role in nutrient cycling and as part of broader cyanobacterial assemblages is significant. No formal IUCN evaluation has been conducted.
