What are the key differences between ticks and spiders in terms of their behavior and physical characteristics?

Ticks and Spiders are both arachnids, but they have key differences in behavior and physical characteristics. Ticks are parasitic and feed on blood, while spiders are predators that hunt and capture their prey. Ticks have a rounded body shape and lack distinct body segments, while spiders have a distinct body with two main segments and eight legs. Additionally, ticks do not spin webs like spiders do to catch their prey.
