Common Paper Nautilus

<em>Argonauta argo</em> is a pelagic cephalopod mollusc in the family Argonautidae, found in open tropical and subtropical ocean waters across Asia and Europe, with records from Norway, Portugal, and Taiwan. Unlike true nautiluses, it belongs to the octopus lineage and produces a thin, papery egg case secreted by the female's webbed arms, which is commonly mistaken for a shell. The species inhabits surface to mid-water oceanic environments and is typically encountered near coastlines following storms or during seasonal current shifts. Females are significantly larger than males and carry the egg case containing developing embryos. The species is carnivorous, typically feeding on small crustaceans, zooplankton, and other small marine invertebrates. The IUCN classifies this species as Least Concern given its wide pelagic distribution. Its occurrence in Norway likely reflects occasional drift individuals carried northward by Atlantic currents rather than a breeding population. Biological traits such as average lifespan, body length, and body weight are not consistently recorded across populations in standardized databases, and detailed dietary studies remain poorly documented at the species level. <em>Argonauta argo</em> is often collected as a natural curiosity for its beautiful egg case.

jaguar

아메리카 대륙에서 가장 큰 고양잇과 동물로, 체중이 최대 100kg에 달하며 단단하고 근육질의 체형과 특유의 로제트 무늬 털가죽을 지닌다. 멕시코에서 남아메리카까지 분포하며, 아마존과 판타날이 주요 서식지다. 뛰어난 수영 실력을 갖춘 최상위 포식자로, 먹이 개체수 조절에 핵심적 역할을 한다. 산림 벌채로 인해 서식 범위가 줄어들어 준위협종으로 분류된다.
