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.

Chroococcus minutus is a cyanobacterium in the family Chroococcaceae, recognized as one of the smaller species in the genus. It is distributed in freshwater habitats across temperate regions, including Scandinavia and northern Europe, where it has been documented in taxonomic surveys of freshwater algae and cyanobacteria. Chroococcus species in general are characterized by their simple morphology — spherical or hemispherical cells, binary fission, and organization into pairs or tetrads within gelatinous sheaths. Chroococcus minutus occurs in the plankton and periphyton of lakes, ponds, and slowly flowing waters with low to moderate nutrient levels. Cyanobacteria of this type play roles in primary production and, in certain metabolically active strains, may contribute to nitrogen fixation in nitrogen-limited aquatic systems. The taxonomy of small-celled Chroococcus species remains challenging, with morphological overlap between species and significant variation in cell size related to environmental conditions and growth stage. Recent molecular studies have revealed that morphologically defined genera such as Chroococcus represent multiple phylogenetic lineages, indicating likely future taxonomic rearrangements. The species is not assessed by the IUCN.
