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.

Chrysochromulina mactra is a marine haptophyte microalga belonging to the genus Chrysochromulina, class Prymnesiophyceae. The epithet mactra, meaning kneading trough or trough-shaped vessel, describes a morphological feature of the organism — likely the shape of a scale element or cellular structure visible through electron microscopy. Within Chrysochromulina, fine-scale ultrastructural characters of the cell surface and appendages are the primary basis for species identification, making high-resolution electron microscopy essential for taxonomic work. C. mactra has been recorded from Norwegian coastal marine environments, a region that has historically served as a major source of newly described haptophyte species due to focused research programs and the ecological richness of Norwegian fjord and shelf waters. These environments are influenced by cold North Atlantic currents and seasonal nutrient dynamics that support productive phytoplankton communities in which nanoplankton species like C. mactra play significant roles. As a member of Prymnesiophyceae, the species possesses chloroplasts with chlorophylls a and c and fucoxanthin-type pigments, enabling photosynthetic carbon fixation. The coiling haptonema is a diagnostic feature of Chrysochromulina distinguishing it from related genera including Prymnesium and Haptolina. C. mactra has not been formally assessed under IUCN criteria and is listed as Not Evaluated. As with most marine nanoplankton, its population status and extinction risk cannot be meaningfully quantified with current survey methods.
