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。

Common Sunda Toad

<em>Duttaphrynus melanostictus</em>, the common Sunda toad, is an amphibian in the family Bufonidae, order Anura. It has a wide natural distribution across South and Southeast Asia, ranging from Pakistan and India through to southern China, the Malay Peninsula, and the Indonesian archipelago, and has also been introduced to Madagascar. The species typically inhabits a broad range of environments including urban areas, agricultural land, forest edges, gardens, and disturbed habitats, demonstrating remarkable adaptability to human-modified landscapes. <em>Duttaphrynus melanostictus</em> is characterized by prominent parotoid glands behind the eyes that secrete toxic compounds serving as a defense against predators, a feature shared with other true toads. It is an opportunistic carnivore, feeding on a variety of invertebrates including insects, worms, and small arthropods. Biological traits including average lifespan under natural conditions, typical body measurements, and specific breeding parameters remain poorly documented. The species is assessed as Least Concern by the IUCN, reflecting its extensive range and high tolerance for habitat modification, though introduced populations in Madagascar represent a potentially invasive concern.
