大翅鯨

座头鲸是大型鲸类中最具杂技表演性的物种之一，以繁殖季节雄性演唱的复杂而神秘的歌声著称，歌声有时持续数小时并随时间演变。体长可达16米，体重30吨，进行着哺乳动物中最长距离的洄游。分布于所有大洋，通过协作泡泡网捕食磷虾和小鱼。种群数量已从历史捕鲸后大体恢复。

Chroococcus minimus is a species of cyanobacteria in the family Chroococcaceae, representing one of the smaller-celled members of the genus, as the specific epithet indicates. Chroococcus is a cosmopolitan cyanobacterial genus found across a wide range of aquatic and moist terrestrial habitats globally. The cells of Chroococcus minimus are spherical, very small in diameter, and occur in pairs or tetrads enclosed within a thin, often inconspicuous mucilaginous sheath. Despite their miniature scale, these organisms are photosynthetically active and contribute to primary production in their aquatic environments. Small-celled cyanobacteria like Chroococcus minimus may dominate the picoplankton fraction of oligotrophic freshwater bodies, where their small cell volume provides a favorable surface area to volume ratio for nutrient uptake in nutrient-limited conditions. Chroococcus minimus has been documented from freshwater habitats in Europe and elsewhere. Identification of small-celled Chroococcus species is challenging due to overlapping morphological characteristics and the influence of environmental conditions on cell dimensions. Molecular phylogenetic studies have substantially revised the taxonomy of coccoid cyanobacteria. The species has not been assessed by the IUCN.
