特徵

泥龜的體型較大,最大的龜殼可達65厘米長,重20公斤。

泥龜的龜殼扁平,呈實灰色或近黑色。胸甲一般呈奶白色。幼龜的龜殼中央起角,外緣有鋸齒,但隨著年紀漸長會逐漸消失。牠們的皮膚與龜殼的顏色相近,頸上及下身有紅色斑紋。雄龜的頭兩側有黃色的斑紋,但雌龜沒有,而且雄龜的尾巴也較長及厚。

繁殖

泥龜於冬天介乎9月至11月築巢。雌龜會走到河岸兩邊平時很少到的地方生蛋,避免氾濫影響,每次會生6-29隻蛋。

保育狀況

泥龜很少飼養的。牠們被過度捕獵作為食物。幼龜及蛋也可以作為食物。牠們被動的天性也是易於被捕獵的原因。牠們被世界自然保護聯盟列為極危,故受到《瀕危野生動植物種國際貿易公約》附錄二的保護,禁止出口。
