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。

Clown beetle

Acritus komai is a minute histerid beetle (family Histeridae) belonging to the subfamily Abraeinae. Members of this subfamily are among the smallest beetles in the family, typically measuring less than 2 mm in length. Like all histerids, A. komai is presumed to be predatory, likely feeding on mites, nematodes, or small dipteran eggs and larvae in decaying organic substrates. The genus Acritus comprises numerous species distributed across multiple continents, and members are often associated with rotting wood, dung, carrion, and fungal fruiting bodies. A. komai appears to have a cosmopolitan or wide distribution, possibly facilitated by passive transport in organic material. The species has not been formally assessed by the IUCN, reflecting the general lack of conservation data for many microhabitat-specialist invertebrates. Its extremely small size and cryptic habits make field observation and population assessment challenging. Systematic studies of this genus rely primarily on detailed morphological examination of antennal club structure, elytral striae, and prosternal keels, which are important diagnostic characters in Histeridae taxonomy.
