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 Spiny Lobster

<em>Palinurus elephas</em>, commonly known as the common spiny lobster, is a large marine crustacean in the family Palinuridae, distributed across the northeastern Atlantic Ocean and Mediterranean Sea. This species typically inhabits rocky and biogenic reef habitats at depths ranging from the shallow subtidal zone to approximately 200 metres, where crevices and caves provide shelter during the day. Its geographic range extends from the British Isles and the Azores southward along the Atlantic coasts of Europe and North Africa, and throughout the Mediterranean. The species has not been formally evaluated under IUCN Red List criteria, though commercial populations have declined significantly across much of its range due to intensive fishing pressure. <em>Palinurus elephas</em> lacks the large claws characteristic of true lobsters, relying instead on long, spiny antennae for defence and sensory purposes. It is omnivorous, typically feeding on molluscs, echinoderms, algae, and organic detritus on the seafloor. The species can reach a total body length of approximately 50 cm and may weigh up to approximately 4 kg in large individuals, though average lifespan measurements remain poorly documented. Spawning occurs in summer, with females carrying egg masses under the abdomen. Commercial fisheries management increasingly focuses on minimum landing sizes and seasonal closures.
