Zoanthus have smaller polyps and reproduce by forming buds from the base of the mated tissue. The species unlike some of the others in the family does not incorporate sediment into it’s base. The oral disk is in the center of tightly packed tentacles and appear in nature in a variety of colors and endless combinations.
Palythoa have larger polyps but are also embedded in a common tissue. The texture of the base of both the Palythoa and Protopalythoa is rough from the incorporation of sand and
sediment directly in the tissue. The assimilation of the material is thought to be both for defense and support. The larger polyps lend themselves to feeding on larger meatier foods.
Protopalythoa much like the Palythoa in size but with the exception that the polyps are not connected to one mass of tissue. Some seem to have less more pointed tentacles in some cases they even alternate up and down.

Palys are bigger than zoo's. You can even feed the palys but the zoo's don't eat if you try to feed it.
Scientifically, Palythoa species have a gritty/grainy coenenchyme (mat/stalk) and Zoanthus species do not take in the gritty material. That is the biggest actual difference. Size has nothing to do with genus, though can give a rough grouping, though very inconsistent. In many cases, lighting and flow control polyp size to a large degree.
