I think Schaums too kinda detailed with the phylum but when it comes to protists they use different names. But Ap cliffs summarized it already. Schaums ecology has some stuff that Cliffs didn't put much detailed on or the other way around. Also I think Schaum's has more detailed stuff about the physiology part (digestive, excretory) But both cliffs and schaums do not have the eyes, ears story part like in kaplan's. Cliffs does not talk about the H, I band and A band in regards to the Muscle part but Schaums do. Schaums has fetal circulation I think (or I'm day dreaming). That's all I can think of for now. lol I need to browse them again.
