Comoro cat shark

<em>Scyliorhinus comoroensis</em>, the Comoro catshark, is a small demersal shark in the family Scyliorhinidae. As its name suggests, it is associated with the waters around the Comoro Islands in the western Indian Ocean, where it was first described from specimens collected in the region. Like other catsharks, it is a bottom-dwelling species adapted to life on or near the seafloor, typically inhabiting continental and insular shelf and slope environments. Biological traits including average lifespan, body length, body weight, and dietary preferences remain poorly documented due to the species' limited range and the scarcity of specimens available for study. Based on comparisons with related scyliorhinid species, it likely feeds on small fish, cephalopods, and invertebrates. The species is currently assessed as Data Deficient by the IUCN, reflecting the limited information available on its distribution, population size, ecology, and response to potential threats such as bycatch in artisanal and commercial fisheries operating in the Comoros region. Dedicated surveys and additional specimen collection are needed to improve knowledge of <em>Scyliorhinus comoroensis</em> and to determine appropriate conservation measures.

Emperor Penguin

세계에서 가장 큰 펭귄인 황제펭귄(Aptenodytes forsteri)은 키가 최대 1.2m에 몸무게가 45kg에 달하며, 지구상에서 가장 혹독한 환경인 남극 대륙에 서식합니다. 영하 60°C 이하의 한겨울 암흑 속에서 번식하며, 수컷이 암컷이 바다에 있는 동안 65일 동안 발 위에서 육아낭 아래에 알 한 개를 품습니다. 수천 마리가 모인 무리에서 개체들이 따뜻한 중심부를 순환하는 이른바 허들링 행동은 협동적 생존의 훌륭한 사례입니다.
