ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

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.
