지구에서 살았던 것으로 알려진 가장 큰 동물로, 대왕고래(Balaenoptera musculus)는 33미터, 200톤에 달할 수 있으며, 심장만도 소형 자동차 무게와 비슷합니다. 모든 대양에 서식하며, 극지방 먹이 지역과 열대 번식 지역 사이를 이동합니다. 하루 최대 4톤의 크릴새우를 섭취하는 여과 섭식자입니다. 20세기 포경으로 인한 거의 멸종 이후 전 세계 개체수가 10,000~25,000마리로 추정되는 멸종위기 종입니다.

Coelosphaerium aerugineum is a colonial planktonic cyanobacterium in the family Merismopediaceae, forming spherical to irregularly shaped gelatinous colonies in which individual cells are arranged in a peripheral layer surrounding a central mucilaginous matrix. Like other members of the genus, C. aerugineum is found in freshwater lakes, ponds, and slow-flowing waters of the temperate zone, including Scandinavia. Cyanobacteria are among the oldest life forms on Earth, contributing to oxygen evolution in ancient oceans, and continue to play fundamental roles in modern aquatic biogeochemistry through nitrogen fixation and primary production. Coelosphaerium species can form blooms under nutrient-enriched eutrophic conditions, although they are generally less notorious for bloom formation than genera such as Microcystis or Dolichospermum. The spherical colonial architecture provides some protection against grazing by zooplankton, while the cells contain gas vesicles that assist in vertical positioning within the water column. Distribution of Coelosphaerium aerugineum spans temperate freshwater habitats across Europe, including northern countries such as Norway and Sweden, where it occurs in lakes and reservoirs during warmer months. No formal conservation assessment has been undertaken for this species, as freshwater cyanobacteria at this taxonomic level are generally not evaluated by the IUCN.
