As a commemoration of the Imperial collection of shells in Vienna, the printed folio of Testacea Musei Caesarei Vindobonensis of 1780, is splendid. The eighteen engraved plates, carefully colored by hand, render individual specimens in the Habsburgs’ K.K. Hof-naturalien-Cabinet as if pieces of jewelry, casting shadows on a plain background of the thick, hand-made paper. Dedicated to the Empress of Austria, Maria Theresa (1717-1780), this production was also a work of science, as the task of arranging the shells in the Cabinet and describing them for publication was given to one of the leading scientists of the day, Ignaz Edler von Born (1742-1791).

Using molecular species delimitation methods, Dr. Fernando Á. Fernández-Álvarez, a post-doc at Institut de Ciències del Mar (CSIC) in Barcelona, and his colleagues[1] found that what is currently described as Ommastrephes bartramii actually represents four different species. After examining previous descriptions in the literature, three synonymized names have been proposed for resurrection accordingly. This research comprises one of four chapters in Fernández-Álvarez’s Ph.D. thesis, and the manuscript is currently under preparation for submission to a journal.

The Biodiversity Heritage Library proved to be a vital resource for these research, allowing Fernández-Álvarez to easily locate literature about relevant synonymized names, many of which were published in the 19th century.

In 1907, the U.S. Bureau of Fisheries—now known as NOAA Fisheries or the National Marine Fisheries Service—embarked on a 2 ½ year research trip to the Philippine and neighboring islands. Of the many research trips conducted on their steamer the USS Albatross, the Philippine expedition resulted in a staggering estimate of 490,000 specimens turned over to the U.S. National Museum, what is now the National Museum of Natural History.

A new land snail species from Laos has been named in honor of the Biodiversity Heritage Library! Vargapupa biheli, a medium-sized, slender turriform species with a well developed basal keel, was described in the article “Revision of the Genus Pseudopomatias and its Relatives (Gastropoda: Cyclophoroidea: Pupinidae” in Zootaxa: 3937(1), 2015, by Barna Páll-Gergely, Zoltán Fehér, András Hunyadi, and Takahiro Asami.

Have you ever collected seashells from the sea shore? Ever wonder where they come from or the former inhabitants? Well, they come from Molluscs. Molluscs are invertebrates that include squid, octopuses, cuttlefish, nudibranchs, snails, slugs, limpets, sea hares, mussels, clams, oysters, scallops, and other lesser known creatures.

Molluscs, belong to the phylum Mollusca, a major division of invertebrates with over 100,000 species, second to Arthropods. Their ability to survive is inspiring. They can be found at all latitudes and in both tropical and temperate regions.
