Carcharhinus galapagensis (Snodgrass & Heller, 1905)

ガラパゴスザメ Carcharhinus galapagensis はメジロザメ属に属するサメの一種。全世界の熱帯の海洋島に生息する。大型で3.0mに達する。一般的なメジロザメ類の形態をしているためドタブカ・オグロメジロザメなどとの区別が難しい。本種を識別できる点として、第一背鰭が高く、その先端がわずかに丸いこと、胸鰭の後端より第一背鰭が後ろにあることが挙げられる。活発な捕食者で大きな集団を作る。主に底生の硬骨魚や頭足類を食べるが、大型個体は海獣なども狙うようになる。胎生で2-3年ごとに4-16匹の仔を産む。大胆で好奇心が強く、攻撃的であるため危険なサメとみなされている。IUCNは保全状況を軽度懸念としている。
