(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.
Examples of these diploblastic creatures can still be found today, in marine and fresh waters throughout the world.
Sponges are diploblastic metazoans that possess no organ systems; their tissues consist of a limited number of cell types that surround and penetrate a mesohyl of collagen.
