Continuing through Ecdysozoa, we will now wrap up clade Scalidophora by examining phylum Priapulida. These are also known as the penis worms, and for good reason, given their distinct morphology. These range quite a bit in size despite only consisting of 22 species, and they are often confused for organisms in other phyla, so let's get a better understanding of them now!
