A ave nacional dos Estados Unidos e símbolo do sucesso conservacionista americano, a águia-careca tem uma envergadura de até 2,4 metros e habita florestas e zonas húmidas próximas de águas abertas em toda a América do Norte. Quase extinta na década de 1960 devido ao envenenamento por DDT e à caça, recuperou de forma notável após as proibições de pesticidas e a Lei das Espécies em Perigo.

common pelican’s foot

<em>Aporrhais pespelecani</em>, commonly known as the common pelican's foot, is a marine gastropod mollusk belonging to the family Aporrhaidae. This distinctive snail is named for its unusual shell shape, which features a flared outer lip with finger-like projections resembling a pelican's webbed foot. It inhabits sandy and muddy substrates of shallow coastal seas, typically found at depths ranging from the intertidal zone to several hundred metres. The species is distributed across temperate European waters, with confirmed records from Belgium, Denmark, Norway, and Sweden, as well as Turkey, indicating a range spanning the northeastern Atlantic and parts of the Mediterranean and Black Sea. <em>Aporrhais pespelecani</em> typically buries itself partially in soft sediments, where it feeds on organic detritus and microalgae. The species is assessed as Least Concern on the IUCN Red List, reflecting its relatively wide distribution and absence of major threats. Biological traits such as average lifespan, body size, and detailed dietary composition remain poorly documented in the scientific literature. Populations are generally considered stable, though localised habitat degradation from coastal development and trawling may pose risks in certain parts of its range.
