🐟Squatina squatina
ホンカスザメ (本糟鮫、Squatina squatina) はカスザメ属に属するサメの一種。北東大西洋の広範囲に分布していた。150mより浅い沿岸の砂泥底に生息する。形態は他のカスザメ類に準じ、エイに似た扁平な体を持つ。形態的特徴としては、体が幅広く太い、髭が円錐状である、大型個体で背面の棘が消失する、頭部側面の皮褶が三角形である、眼が噴水孔より小さい、などがあり、これらの点で近縁種のトゲナシカスザメ・トゲカスザメと区別できる。体色は灰から茶褐色で、 多数の細かい黒斑が散らばる。 他のカスザメ類と同様に夜行性の待ち伏せ型捕食者で、主に魚類を食べる。刺激されると人にも攻撃することがある。無胎盤性の胎生で、数年おきに7–25匹の仔魚を産む。古代ギリシャから長く利用されてきたが、ヨーロッパでは20世紀以降の商業漁業の影響でほとんど見られなくなっており、IUCNは保全状況を絶滅寸前としている。
