Oniscidea
Sign in to saveAlso known as woodlouse, sow bug
Woodlice are terrestrial isopods in the suborder Oniscidea. Their name is derived from being often found in old wood, and from louse, a parasitic insect, although woodlice are neither parasitic nor insects. Other common names include slater, sow bug, and wood pig, common names varying widely by region.
Oniscidea is a suborder of small terrestrial animals commonly known as woodlice, pill bugs, or slaters, which are often found in damp wood and soil despite their misleading name suggesting they are parasitic insects. These creatures are significant as common decomposers in ecosystems and serve as indicators of environmental conditions, though they remain largely misunderstood due to their insect-like appearance and association with decaying wood.

ワラジムシ亜目（ワラジムシあもく、Oniscidea）とは、ダンゴムシやワラジムシ、フナムシなどの陸生の甲殻類の分類名である。すべて炭酸カルシウムを含む硬い外骨格を備えており、体節は頭部1節・胸部7節・腹部5節、胸部の7節に1対ずつ計14本の脚を持つ。 陸上で生活するが、乾燥に弱いため、石や木材の下などの湿度の高い場所で見つかる。植物性の腐敗物などを摂食するデトリタス（腐食）食性である。 呼吸は、腹肢の一部にある白体（偽気管）という器官を通じて行う。 捕食者に脅かされた場合、硬い外皮を外側にしてボール状に丸くなる種類もある。ワラジムシ亜目に属するダンゴムシなどの名前はこのような能力に由来する。オカダンゴムシの学名 Armadillidium vulgare も硬い外皮を外側にして体を丸める哺乳類のアルマジロに由来する。

Woodlice are terrestrial isopods in the suborder Oniscidea. Their name is derived from being often found in old wood, and from louse, a parasitic insect, although woodlice are neither parasitic nor insects. Other common names include slater, sow bug, and wood pig, common names varying widely by region.
Woodlice are suggested to have colonised land during the late Paleozoic based on molecular clock analysis, though the oldest known fossils are from the mid-Cretaceous period around 100 million years ago. This makes them unusual among the crustaceans, being one of the few lineages to have transitioned into a fully terrestrial environment.
