Arachnids are spiders, harvestmen, mites and ticks. You may confuse these animals with insects but arachnids do not have antennas. All arachnids have eight legs and they do not have wings. Scientists have identified over 90,000 different species of arachnid.

They can be found throughout the world, however most are found on land. Most scorpions live in tropical regions while many spiders are found in northern areas. Ticks and mites live in soil or on plants, but some live on or in animals. You may have heard that your dog has a tick before?

There are hundreds of thousands of species of arachnids. Arachnids are predators on insects and other invertebrates. The exceptions are many mites, who feed on all sorts of things, such as fungus, plants, dead animals and bacteria.

Most arachnids eat smaller arthropods. Arachnids do not have jaws, so they must break down their food by tearing it into small pieces. They break down these pieces that have digestive fluids to allow them to be easier to digest. Instead of eating they simply such up these digestive fluids.

Like all arthropods, arachnids have segmented bodies, a hard outer covering called an exoskeleton, and jointed limbs. In most arachnids, three pairs of the limbs are their six legs to walk on. The other limbs are used for tasks such as holding and crushing prey.
