Mollusk Diversity

Go digging for clams with Field Museum Curator and zoologist, Dr. Rüdiger Bieler and his international team of scientists as they study the evolution of mollusks—the largest group of animals in the oceans and the second largest animal group in the world! You’ll discover how mapping out the relationships between bivalve mollusks like clams and scallops helps us to understand evolutionary pathways and track the development of genes over time.

4. Dredging Deeper Waters

Discover how Dr. Bieler’s team uses oceanographic dredging equipment to collect mollusks from the soft-bottomed ocean floor along Australia’s Moreton Bay. You’ll also see some of the fascinating clams, oysters, and shipworms collected during scuba-diving missions at coral reefs!
