Hohojirozame

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate grasslands and steppes, among 9 distinct biome types spanning the Indomalayan and Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Chile, Norway, Portugal, and Taiwan. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Collins' Squirrel Monkey

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Hohojirozame

地球上で最大の捕食性魚類であるホホジロザメは、全世界の主要な大洋の冷涼な沿岸・外洋域に生息し、体長6メートル、体重2,000キログラムに達することがあります。海洋哺乳類、大型魚類、海鳥を主な獲物として下方からの待ち伏せ攻撃を行う最上位捕食者です。その恐ろしい評判にもかかわらず、人間への非挑発的な攻撃は極めてまれです。フカヒレ採取、混獲、目的的漁獲によって個体数が減少しており、多くの地域で法的保護を受けているにもかかわらず危急（VU）に分類されています。

Collins' Squirrel Monkey

<em>Saimiri collinsi</em>, commonly known as Collins' Squirrel Monkey, is a primate species belonging to the genus <em>Saimiri</em> 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 <em>Saimiri collinsi</em> continues to refine understanding of squirrel monkey diversity.
