Integrated genomics database for Mollusca

Welcome to MolluscDB!

Mollusca is the second largest animal phylum and represents one of the most evolutionarily successful animal groups. MolluscDB represents the most comprehensive genomics database specifically for molluscs, by integrating current large amounts of genomic resources and providing convenient tools for multi-level integrative and comparative analyses. MolluscDB provides a highly-valuable, open-access genomics platform for molluscan research community, by allowing for user-defined comprehensive analysis of ever-growing molluscan genomic resources, and expediting new scientific discoveries for this super species-rich but genomically poorly explored animal phylum.
