Marine Invertebrate Neoextinctions: An Update and Call for Inventories of Globally Missing Species

The register of global extinctions marine invertebrates in historical time is updated. Three gastropod and one insect species are removed from the list extinct species, while two gastropods, echinoderm, three parasites (a nematode, an amphipod, a louse) added. nine now recognized likely represent minute fraction actual number that have gone extinct. Urgently needed for evaluation inventories globally missing across wide range phyla. Many such known to systematists, but either rarely flagged, or if mentioned, not presented as potentially taxa.
