From crabs and clams to snails and seastars, the Marine collections show the diversity of life below the seas.

A small number of the marine collections are shown in the Discovery and Victorian study galleries, and the spirit specimen display at the museum. However these are only a tiny part of our marine collections. The collections house several hundred thousand specimens of marine molluscs from primitive bryozoans and microscopic foraminifera to armoured lobsters and highly evolved cephalopods.

A wider selection of objects are used in events and temporary displays to tell important stories about our changing world. These have included the bleaching of coral reefs, and the over fishing of krill.
