What is an Arachnid?
Definition of an ARACHNID
1: a kind of animal that has eight legs and a body formed of two parts
2: any of a class (Arachnida) of arthropods comprising chiefly terrestrial invertebrates, including the spider, scorpions, mites and ticks, and having a segmented body divided into two regions of which the anterior bears four pairs of legs but no antennae.
(reference: Merriam-Webster Online Dictionary)
There are over 100,000 species of arachnid species, including ticks, mites, scorpions, tarantulas and spiders.
All arachnids live on land but there are exceptions, for example the Diving Bell Spider (Argyroneta aquatica) of northern and central Europe and northern Asia.
Arachnids have eight legs which distinguishes them from insects which have only six legs.
