See answer below:

Explanation:

Open circulatory systems are featured primarily in Kingdom Animalia, Phylum Arthropoda. This includes creatures such as crayfish, lobsters, spiders, and other insects.

Open circulatory systems are blood systems that allow blood to flow out of large veins, and fill various body cavities so that tissue can absorb oxygen and nutrients directly from the blood. By the flow of gravity, it collects in a vein running on the bottom of the athropod, and gets transported back to the heart. This is often why arthropods protect their underbellies from harm.
