Arachnids encyclopedia

Explore the 11 Animalpedia species classified as arachnids: characteristics, diet, habitat, behaviour and conservation status.

Arachnids are invertebrate animals with eight legs, whose body is divided into two parts. Unlike insects, they have neither wings nor antennae. Most are land-dwelling predators. The group brings together spiders and scorpions, as well as ticks and mites, some of which cause health problems in domestic animals.
