Common Pondskater

<em>Gerris lacustris</em>, the common pondskater, is an aquatic insect in the family Gerridae, well known for its remarkable ability to walk and skate across the surface of still or slow-moving freshwater bodies using surface tension. Microscopic water-repellent hairs on its legs trap air and prevent the insect from breaking the water film, allowing it to detect vibrations from struggling prey and move rapidly across the water surface. The species is a predator and scavenger, typically feeding on small invertebrates, including other insects, that fall onto or become trapped at the water surface. <em>Gerris lacustris</em> is distributed across Europe, with confirmed records from Belgium, Denmark, Norway, and Sweden, and is among the most commonly encountered water striders in temperate European ponds, lakes, and slow-flowing rivers. It is assessed as Least Concern on the IUCN Red List, reflecting widespread abundance and absence of major conservation threats. The species overwinters as an adult in terrestrial habitats and returns to water in spring. Biological traits such as average adult lifespan, precise body dimensions, body mass, and detailed dietary composition remain poorly documented in the scientific literature. Adults are capable of flight and can colonise new water bodies effectively.

Lion

아프리카 최대의 야생 고양이과 동물로 최대 250kg에 달하며, 사하라 사막 이남의 사바나와 초원에서 무리 생활을 하는 유일한 사회성 고양이과 동물입니다. 수컷은 상징적인 갈기로 구별됩니다. 최상위 포식자로서 초식동물 개체군을 조절하고 생태계 균형을 유지합니다. 서식지 손실과 인간-야생동물 충돌로 인해 취약 등급으로 분류됩니다.
