No, some invertebrates lack circulatory systems all together such as cnidarians, psudocoelomates and poriferas (sponges). Most of these use tubes that link their internal body to the external environment or they use a gastrovascular cavity. Some have closed circulatory systems such as mollusks (not cephlapods) and anthropods, the pump a fluid that lacks the complete distinction between extracellular fluid and circulating fluid thus this fluid is called Hemolymph.
