Collins' Squirrel Monkey

Saimiri collinsi, commonly known as Collins' Squirrel Monkey, is a primate species belonging to the genus Saimiri within the family Cebidae. Squirrel monkeys are small, highly social New World primates known for their agility in forest canopies and their complex group dynamics. This species is assessed as Least Concern by major conservation bodies, indicating that its populations are not currently considered at high risk of decline, though ongoing deforestation and habitat fragmentation in Amazonian regions may affect future population stability. Collins' Squirrel Monkey inhabits diverse terrestrial and aquatic-adjacent environments typical of tropical forest ecosystems in South America. Specific country-level distributional records are not detailed in current documentation. Dietary information specific to this species has not been recorded, though squirrel monkeys in general are omnivorous, consuming insects, small vertebrates, fruits, and other plant material. Biological traits of this species remain poorly documented in the scientific literature. Research into the taxonomy and ecology of Saimiri collinsi continues to refine understanding of squirrel monkey diversity.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
