毛马陆目学名Polyxenida)为倍足纲下的一个,最大的特征在于在柔软无钙化的外壳上布满了刚毛。毛马陆目下共有4科至少167种,也是毛尾马陆亚纲下唯一的现存目。

描述

[编辑]

毛马陆与其他马陆最大的差异在于牠们具有柔软无钙化的外骨骼、甲壳上布满了刚毛、较少的脚数量(不超过17对)、且雄性缺乏生殖肢。体型偏小,体长最长不会超过7毫米(0.28英寸)。

防御机制

[编辑]

毛马陆缺乏一般马陆所具有的坚硬外骨骼与化学防御机制[1],而是具有一套独特的自我防卫方法:牠们身上具倒刺的纲毛十分容易脱落,能残留在掠食性昆虫的附肢与口器上,进而阻碍牠们的行动[2]

繁殖

[编辑]

雄性毛马陆缺乏一般马陆用来传输精子的生殖肢英语Gonopod,因此牠们只能透过间接的方式提供精子。雄性会丢下精包,并交由雌性拾取[3]

许多种的毛马陆也能进行单性生殖,当雄性个体稀少时,雌性依然有能力在未受精的情况下产卵并孵化下一代[4]

分类学

[编辑]
Phryssonotus brevicapensis合马陆科英语Synxenidae),2011年发现于南非[5]

毛马陆为毛尾马陆亚纲现存的唯一目,且为所有马陆所属亚纲的基群。毛尾马陆亚纲为所有现存马陆的姊妹群,包括五带马陆下纲英语Pentazonia蠕形马陆下纲英语Helminthomorpha[6][7]

2003年,毛马陆目包含了159种有效种及亚种[8],但是自2010年以来,已陆续发表了至少8个新种[5][9][10]

化石纪录

[编辑]

最早的毛马陆化石发现于黎巴嫩白垩纪早期的一个琥珀之中[11]

部分科学家将已灭绝的节肋目Eoarthropleurida英语Eoarthropleurida并入毛尾马陆亚纲之下,作为毛马陆目的姊妹群[12][13]
