I WONDER - What Do Arachnids Eat?

Arachnids are primarily predators of insects and other invertebrates, with mites being an exception as they feed on various substances like fungus and bacteria. Most arachnids consume smaller arthropods. They lack jaws and must tear their food into small pieces, using digestive fluids to break it down further. Instead of eating solid food, they suck up these fluids.

What is the role of digestive fluids in the feeding process of arachnids?

In what way do arachnids consume their food?
