UF Invertebrate Zoology

OBIS USA Open in mapper Explore occurrences

The UF Invertebrate collection holds ~580,000 databased lots of mollusks and marine invertebrates. It began as a Malacology collection almost 100 years ago and the collection is particularly strong in non-marine mollusks. Approximately ~85% of the holdings are mollusks but since 2000 the collection was expanded to cover all invertebrate phyla, focusing on marine taxa. Today it holds >40,000 species from 28 phyla.
