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。

Colombian Four-eyed Frog

<em>Pleurodema brachyops</em>, commonly known as the Colombian Four-eyed Frog, is an amphibian species belonging to the genus <em>Pleurodema</em> within the family Leptodactylidae. The common name refers to the conspicuous glandular swellings on the posterior of the body that resemble eyes, a defensive adaptation thought to deter predators by mimicking a larger, more threatening animal. This species is assessed as Least Concern by major conservation bodies, indicating that its populations are not currently at elevated risk. It has been documented in Colombia and Venezuela, where it inhabits freshwater-associated environments, moist forests, and wetland habitats. Frogs of this genus are typically terrestrial, breeding in temporary pools and humid environments during the wet season. Dietary information specific to this species has not been documented, though small leptodactylid frogs generally prey on invertebrates. Biological traits of this species remain poorly documented in the scientific literature. The species' striking antipredator morphology makes it a subject of interest in herpetological research on defensive behaviors in amphibians.
