Chrysolykos calceatus is a freshwater chrysophyte microalga in the genus Chrysolykos, class Chrysophyceae, order Chromulinales. The genus Chrysolykos belongs to the loricate chrysophytes, a group of golden algae enclosed within a rigid or semi-rigid outer case through which flagella emerge. The specific epithet calceatus — meaning shoed or boot-shaped — describes the characteristic shape of the lorica in this species, which resembles a shoe or boot in lateral profile, a morphology distinctive enough to separate it from the angular profile of C. angulatus and the flattened form of C. complanatus. C. calceatus has been recorded from Norwegian freshwater environments, part of the documentation of chrysophyte diversity in cold Scandinavian lake systems. Scandinavian oligotrophic lakes are important habitats for loricate chrysophytes, which thrive in their clear, low-nutrient waters during stratified warm seasons when competition from larger algae is reduced. The species is a nanoplankton organism engaged in photosynthesis using the chrysophyte pigment complement, and may additionally practice phagotrophy on bacteria and small organic particles. Stomatocyst formation — the production of siliceous resting cysts — is a feature shared across many chrysophytes and may occur in C. calceatus, providing resistance to unfavorable seasonal conditions such as winter ice cover or summer thermal stratification. C. calceatus has not been formally assessed under IUCN criteria and is classified as Not Evaluated. Documentation of this species contributes to knowledge of freshwater microalgal biodiversity in boreal and subarctic ecosystems.

长颈鹿（Giraffa camelopardalis）是地球上最高的动物，身高可达5.5米，体重最重可达1,750千克。其细长的颈部——与所有哺乳动物一样包含七块颈椎——是为了在非洲稀树草原和林地取食金合欢树而进化的。长颈鹿是社会性动物，生活在无固定纽带的松散兽群中，通过次声波和肢体语言进行交流。由于栖息地丧失和偷猎，种群持续减少，被列为易危。
