🐟Chinese paddlefish
ハシナガチョウザメ（Psephurus gladius、簡体字: 白鲟; 繁体字: 白鱘; 拼音: báixún）は、軟質亜綱チョウザメ目ヘラチョウザメ科に分類される魚の一種である。絶滅種。完新世まで生存したヘラチョウザメ科魚類は本種とヘラチョウザメの2種のみである。最大体重300キログラム (kg)、最大全長3メートル (m) を超える世界最大級の淡水魚だった。中国の長江と黄河流域に生息しており、河口に近い沿岸域でも見られた。遡河回遊性で、繁殖のため河を遡上していた。乱獲や、葛洲ダムや三峡ダムなどのダム建設により繁殖のための回遊が阻害されたことが原因で個体数を減らしており、国際自然保護連合 (IUCN) は近絶滅種に分類していた。2019年の論文により絶滅が確定的であると判断され、2022年に絶滅が宣言された。
