American Bald Eagle

흰머리독수리(Haliaeetus leucocephalus)는 미국의 국조이자 미국 자연 보전 성공의 상징으로, 날개 폭이 최대 2.4미터에 달하며 북미 전역의 수변 삼림과 습지에 서식한다. 주로 물고기를 포식하는 강력한 공중 포식자이자 청소 동물로, DDT 오염과 남획으로 1960년대에 멸종 위기에 처했으나 농약 사용 금지와 멸종위기종보호법 시행 이후 극적으로 개체수가 회복되었다.

common European cockle

<em>Cerastoderma edule</em>, the common European cockle, is an intertidal bivalve mollusc in the family Cardiidae, classified as Least Concern by the IUCN Red List. The species is native to European coastal waters and has been documented in Belgium, Denmark, Iceland, Norway, and Sweden, where it typically inhabits sandy and muddy intertidal and shallow subtidal sediments in estuaries, bays, and open coastlines. <em>Cerastoderma edule</em> is a filter feeder, drawing in seawater through its siphons to extract phytoplankton, bacteria, and organic particles. It is recognized by its distinctive ribbed, cream-colored shell with radiating ridges and concentric growth lines. Cockles are a keystone species in many European coastal ecosystems, providing an important food source for shorebirds such as oystercatchers and knots, predatory fish, crabs, and starfish. The species also supports one of the most commercially significant shellfish fisheries in Europe, with large-scale harvesting operations in the UK, the Netherlands, and Ireland. Dense cockle beds stabilize intertidal sediments and contribute to benthic productivity. Population dynamics are closely linked to sea surface temperature, salinity, and sediment availability, making this species a useful indicator of estuarine ecosystem health. Biological traits of this species remain poorly documented in the scientific literature.
