鳞足螺

鳞足螺（学名：Chrysomallon squamiferum），又名鳞角腹足蜗牛[3]，是一种生活在深海热泉的海螺，属于Peltospiridae（英语：Peltospiridae）科的海洋腹足纲软体动物物种[2]，也是鳞足螺属（Chrysomallon）的单型种。本物种不单与其他深海腹足纲物种相异甚远，就连同属Neomphaloidea总科的物种亦与之相异甚远[4]。2019年，因深海资源开发将对热泉区带来的环境影响，它以濒危（endangered，指很可能会绝灭的物种）[5]的级别被列入国际自然保护联盟（IUCN）的濒危物种红色名录[6][7]。

异名[2]
  • Crysomallon squamiferum（拼写错误）

其螺壳虽然亦是与其他腹足纲物种一样由三层组成，但部分的化学构成有所不同：最外一层由硫化铁组成，中间一层相当于其他物种的有机外壳膜，而最里层则由霰石构成。其腹足亦很特别，裹有矿物化了的铁构成的鳞甲。这亦是本物种的名称由来。

其异常大的食道腺住有共生性Γ-变形菌，；而其心脏按其身体体型与其他动物来比较亦是异常的大，占了整个身体的4%体积[4]。

其生活在印度洋海域2400米到2800米深的深海热泉[2]。该物种被首次发现于2001年，位于印度洋中洋脊2420米深深海热泉的黑色海底烟柱旁[8]。该物种随后也在Solitaire与Longqi区域被发现[9][10][11]。
