giraffe

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 5 distinct biome types within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Ecuador. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Coelosphaerium aerugineum is a colonial planktonic cyanobacterium in the family Merismopediaceae, forming spherical to irregularly shaped gelatinous colonies in which individual cells are arranged in a peripheral layer surrounding a central mucilaginous matrix. Like other members of the genus, C. aerugineum is found in freshwater lakes, ponds, and slow-flowing waters of the temperate zone, including Scandinavia. Cyanobacteria are among the oldest life forms on Earth, contributing to oxygen evolution in ancient oceans, and continue to play fundamental roles in modern aquatic biogeochemistry through nitrogen fixation and primary production. Coelosphaerium species can form blooms under nutrient-enriched eutrophic conditions, although they are generally less notorious for bloom formation than genera such as Microcystis or Dolichospermum. The spherical colonial architecture provides some protection against grazing by zooplankton, while the cells contain gas vesicles that assist in vertical positioning within the water column. Distribution of Coelosphaerium aerugineum spans temperate freshwater habitats across Europe, including northern countries such as Norway and Sweden, where it occurs in lakes and reservoirs during warmer months. No formal conservation assessment has been undertaken for this species, as freshwater cyanobacteria at this taxonomic level are generally not evaluated by the IUCN.

giraffe

地球上で最も背の高い動物であるキリン（Giraffa camelopardalis）は体高が5.5mに達し、体重は最大1,750kgにもなる。すべての哺乳類と同じ7個の頸椎からなる長い首は、アフリカのサバンナや疎林のアカシアの木に食物を求めて進化した。永続的な絆を持たない緩やかな群れで生活する社会的動物で、超低周波音と身振りで意思疎通する。生息地の喪失と密猟により個体数が減少している危急種である。
