解剖 编辑

尾腔綱物種有細小(1-30 mm)的體型,是一类主要在深海生活的軟體動物。這些動物的身體就像蟲子,沒有外殻骨板或肉足之類具特徵的身體部份,只是有鱗片或鈣質的骨片英语sclerite,以幫助移動。

生態 编辑

尾腔綱物種通過在軟泥沙挖掘出洞穴而在裡面居住,進食時會垂直躺在沉積物中只露出口器,吞吃在附近通過的有機碎屑。在有性生殖過程中,雌性產卵受精和育卵,直至幼蟲時就可自由游動。

食性 编辑

本綱物種以有孔蟲foramanifera)為食[2]

分類 编辑

本綱物種過往常與溝腹綱Solenogastres)合稱為无板纲Aplacophora),但有其他文獻指無板綱乃並系群[3]

過往當生物分類學純綷以形態學為分類準則之時,無板綱物種曾被以為跟海參同類,這一點可在1987年之前的分類中看見。從1987年起,無板綱得到確認為軟體動物門​一個獨立的綱。當時的无板纲由兩個群組成,分別為[4]

這兩個群最初以為只是並系群,但近年的分子數據支持兩個群是單系群的論說[8][9]。而從分子數據及化石的分析,無板綱很大可能是從多板纲演化,只是後來這些「板」都退化了[8][9][10][11][12]。後來溝腹亞綱和尾腔亞綱都升格至綱級。

現時本綱包括六個科、15個屬、約150個物種,分別如下:
