Carcharhinus obscurus (Lesueur, 1818)

ドタブカ Carcharhinus obscurus はメジロザメ属に属するサメの一種。全世界の温帯〜熱帯海域に分布し、長距離回遊を行う。メジロザメ属では最大種の1つで、最大で全長4.0 m、体重347 kgに達する。流線型の体、短い吻、長い鎌型の胸鰭、背鰭間の隆起が特徴。 成体は頂点捕食者であり、食性は非常に多様である。胎生で、22-24か月の妊娠期間を経て3-14匹の仔魚を産む。繁殖周期は3年だが、雌は雄の精子を貯めておき、妊娠に適した状況を選ぶことができる。成長は遅く、性成熟まで20年かかる。 人に危害を加える可能性があるが、事例は少ない。繁殖力が低く乱獲に弱いが、ふかひれや肝油のために高値で取引されている。このためIUCNは保全状況を絶滅危惧種としている。
