혹등고래는 대형 고래 중 가장 활발한 곡예를 선보이는 종으로, 번식기에 수컷이 부르는 복잡하고 신비로운 노래로 유명합니다. 일부는 몇 시간씩 지속되며 시간이 지남에 따라 진화합니다. 체장 16미터, 체중 30톤에 달하며 포유류 중 가장 긴 이주를 수행합니다. 모든 대양에서 발견되며 크릴과 작은 물고기를 협동 거품그물 먹이 방식으로 포식합니다. 과거 포경으로 크게 감소했던 개체군이 대부분 회복되었습니다.

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.
