they have a closed circulatory sytsem:]yur welcome..... Sorry, this answer is very incorrect. A closed circulatory system means that the blood is contained within blood vessels, which the heart is able to pump/move through the tissues for very efficient gas exchange. Sponges DO NOT have this.

So this means that sponges do not have an open or a closed circulatory system, because they don't have one at all.
