ARTHROPODA
Examples: Ants, flies, cockroaches, shrimps, crabs, spiders and scorpions
Arthoropods are animals that have a backbone (almost 97% of all animal species have a backbone) with repeated sections in the body with joined limbs. There are about 1,170,000 known species and make up for about 80% of all living species. There was a study that estimated there can be around 5-10 million arthropods that are discovered and undiscovered. An arthropod has a segmented body covered by an exoskeleton (outside part of an animal that serves as protection) made from chitin, (a function of glucose) along with some other chemicals.

CIRCULATORY SYSTEM
The species that are part of the arthropod phylum are very similar to the species from the mollusk system. The species in the arthropoda system have an open circulatory system. The circulatory system helps give oxygen to the entire body and disposes the carbon dioxide. Hemolymph (blood)
and go to the lacunas (cavities) draining and irrigating tissues. Insects do not have respiratory pigments because their blood does not carry any oxygen. Although, all arthropods have a heart!
