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.

giraffe

지구상에서 가장 키가 큰 동물인 기린(Giraffa camelopardalis)은 키가 5.5m에 달하고 체중이 최대 1,750kg에 이를 수 있다. 모든 포유류와 같이 7개의 경추로 이루어진 긴 목은 아프리카 사바나와 산림의 아카시아 나무 먹이 섭취를 위해 진화했다. 영구적인 결속 없이 느슨한 무리를 이루며 생활하는 사회적 동물로, 초저주파음과 몸짓으로 소통한다. 서식지 상실과 밀렵으로 개체군이 감소하고 있는 취약 종이다.
