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。

Choco Yellow-shouldered Bat

The Choco Yellow-shouldered Bat (Sturnira koopmanhilli) is a medium-sized frugivorous bat in the family Phyllostomidae, endemic to the Chocó biogeographic region of northwestern South America, where it occurs in the humid forests of the Pacific slope of Colombia and adjacent Ecuador. It belongs to the genus Sturnira — the yellow-shouldered bats — characterised by males bearing distinctive yellowish, orange, or reddish shoulder glands (from which the group's name derives), robust bodies, and rounded ears. Like all Sturnira, this species is primarily frugivorous, consuming a wide range of small, soft fruits from pioneer and forest trees, and plays an important role as a seed disperser in disturbed forest patches and forest edges. The diet of Solanaceae (nightshade family) fruits is particularly typical of the genus, and Sturnira bats are considered the primary dispersers of many pioneer Solanum species in Neotropical secondary succession, contributing directly to forest regeneration. The IUCN classifies the Choco Yellow-shouldered Bat as Data Deficient, reflecting significant uncertainty about the species' distribution limits, population size, and ecological requirements. The Chocó region continues to experience rapid deforestation, which threatens frugivorous bat diversity even where individual species lack adequate data for formal threat assessment.
