Overview
Spiders are a group of Arachnida. Spiders make use of silk that they spin to fly or catch insects. Most spiders are terrestrial, but some have adapted to freshwater by trapping air bubbles and carrying these bubbles with them. Spiders occur worldwide and about 34,000 species have been identified. Spiders have eight legs, anterior appendages bearing fangs and poison glands, and specialized reproductive organs on the second second appendages of the male. Most spiders have a body length of less than 1 cm, but the largest spider has a body length of about 9 cm. Spider leg length, however, can be much greater than that. Spiders are carnivorous and feed on living prey. The bite of a spider can be painful, but most are too small to break the human skin. Even fewer spiders are dangerous to humans.
