The Ancestor’s Tale, Rendezvous 30: Placozoans (Trichoplax)
There really isn’t much to them. They’re basically like amoeba but multi-cellular. They have two layers. It is believed that the top side is for protection while the bottom side is for consumption. There seems to be no head. It just grows arbitrarily. It apparently looks like a jellyfish larva so it was mistakenly classified as that until modern molecular techniques told a different story. They are the only species in their own phylum.
