大型クジラの中で最も曲芸的なクジラのひとつであるザトウクジラは、繁殖期にオスが歌う複雑で神秘的な歌で知られており、数時間にわたって続き時間をかけて変化していきます。体長16m、体重30トンに達し、哺乳類の中で最長の回遊を行います。全海洋に分布し、協調的なバブルネット採餌でオキアミや小魚を捕食します。歴史的な捕鯨後の個体数はおおむね回復しています。

Chrysochromulina parva is a small haptophyte microalga belonging to the genus Chrysochromulina in the family Prymnesiaceae. The specific epithet parva (Latin: small) denotes its cell dimensions relative to other congeners. Structurally, cells possess two unequal flagella and a haptonema, the three-membrane-bound appendage that defines the class Haptophyta and provides the genus with its feeding and attachment capabilities. Organic scales cover the entire cell surface, and their ultrastructure is examined by electron microscopy for species identification. C. parva inhabits marine photic-zone waters in temperate and cold seas, where it forms part of the nanoplankton community. Haptophytes as a group contribute substantially to global marine primary production and produce significant quantities of dimethylsulfoniopropionate (DMSP), a compound with important implications for climate regulation via its atmospheric breakdown product dimethylsulfide. C. parva has not been formally assessed for conservation status and is listed as Not Evaluated by the IUCN. Like most free-living protists, it lacks the discrete geographic range limits that make conventional threat categorization applicable. Molecular surveys continue to expand knowledge of Chrysochromulina diversity in undersampled ocean regions.
