Most arthropods utilize legs or fins to move, but some of the following animals have unusual movement systems; some clams can jump, squid use biological jet engines to shoot water out of their bodies and propel themselves, extinct anomalocaris used flat rows of spikes made of chitin (typical arthropod exoskeleton material) to propel themselves by doing a wave motion that slowly, but effectively, through the water by pushing water behind themselves. But sometimes sacrifices energy to accelerate.

Arthropods have exoskeletons made of chitin. However, chitin is not a protein. It is actually a derivative of glucose, which is a carbohydrate.

Earthworms decompose dead organisms
Arthropods and mollusks have an open circulatory system, where blood (hemolymph) is not confined exclusively to vessels but bathes the organs directly in a hemocoel. In arthropods, such as insects and crustaceans, a dorsal heart pumps hemolymph through vessels into the body cavity, while in mollusks, the heart pumps hemolymph through a series of sinuses. This system allows for efficient nutrient and gas exchange despite the lack of a closed network. However, some cephalopod mollusks, like octopuses, possess a closed circulatory system for more efficient oxygen transport.
No, not all. Remember some arthropods are aquatic; the spiracle/trachea/tracheole system utilized by terrestrial insects is largely replaced by gills in marine arthropods.

Yes, chitin is a polysaccharide found in the exoskeletons of arthropods and cell walls of fungi. It is not a protein.

They can be found almost any shelled mollusk such as the pearl oyster
Since prokaryotic cells do not have complex organelles such as a nucleus or mitochondria as do their counterparts, the eukaryotic cells. The electron transport system (ETS) for bacteria is found on the inner membrane.
