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.

Tiger

지구상 가장 큰 야생 고양잇과 동물로, 무게가 300kg을 초과할 수 있으며 러시아 극동에서 동남아시아에 걸친 산림에 서식한다. 얼룩진 빛 속에서 위장 효과를 주는 독특한 주황색과 검정 줄무늬 털을 가진 단독 매복 포식자다. 밀렵과 삼림 파괴로 야생 개체수가 4,000마리 미만으로 감소한 심각한 위기(CR) 종이다.
