What is another word for solenogastres?
Pronunciation: [sˈə͡ʊlnəɡˌastəz] (IPA) 
Solenogastres is a taxonomic class of small, worm-like marine invertebrates that lack shells, gills and other organs that are normally found in related mollusks. Synonyms for Solenogastres include neomeniidans, tusk shells, aplacophorans, and aculiferans. They are a relatively old group of animals that appear to have diverged from their mollusk ancestors around 500 million years ago. Generally, Solenogastres are known to be burrowing animals, living in the substrate within the depths of the ocean. There is still much that is not known about these fascinating creatures, and so their synonyms reflect the continued study and interest in these elusive and important invertebrates.
