African elephant

아프리카코끼리(Loxodonta africana)는 지구상에서 가장 큰 육상 동물로, 최대 7,000 kg에 달하며 사하라 이남 아프리카의 사바나, 삼림, 습지에 서식한다. 뛰어난 지능을 가지며, 모계를 중심으로 한 복잡한 사회 구조를 이루고 초저주파음, 울음소리, 촉각을 통해 의사소통한다. 나무를 쓰러뜨리고 물웅덩이를 파며 씨앗을 산포하는 생태계 엔지니어로, 현재 취약(VU) 종으로 분류되며 상아 밀렵과 서식지 손실로 인해 개체수가 감소하고 있다.

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.
