8本の脚と2つの体節からなる節足動物。翅はなく、クモの巣を使って狩りや生活を行う。クモの巣は非常に粘り気強く丈夫なため、獲物を効果的に捕獲できる。一部の種は毒を使って獲物を麻痺させる。森、草原、家の周囲などさまざまな環境に生息し、狩りの方法によって投網クモや待機クモなどに分類される。
An arthropod composed of eight legs and two body segments, without wings, uses spider web for hunting and life. The spider web is very sticky and tough, allowing prey to be captured effectively, and some species use venom to paralyze their prey. They inhabit various environments such as forests, grasslands, and around houses, and are classified as net spiders or long-jawed spiders depending on their hunting method.
