2004) argued that animals lacking a coelom, including all diploblastic animals such as cnidarians, would not benefit from production of anti-microbial peptides--a hallmark of Toll-receptor-mediated innate immunity--because diploblasts lack an internal body compartment (namely, the coelom) into which these proteins could be secreted.
