The Royal Albert Memorial Museum and Art Gallery (RAMM) in Exeter cares for over 300 specimens of starfish and their relatives from the HMS Challenger (1872-76) voyage.

HMS Challenger and RAMM

Walter Percy Sladen was a world expert on echinoderms (starfish, sea urchins and their relatives). He wrote the report on the Asteroidea (starfish) collected during the voyage and produced the accompanying volume of illustrations.

He had a large collection of echinoderms which were donated to RAMM after his death. This included some of the specimens he studied from HMS Challenger. RAMM also has his extensive library of books including all 50 Challenger Report volumes and many rare papers and publications on echinoderms.

HMS Challenger on display

Constance Sladen paid for a gallery to be built at RAMM in her husband’s memory. Sladen’s Study has altered very little since it was created in about 1910. Many of the specimens on display are from HMS Challenger and are clearly marked. Two of the original HMS Challenger reports are also displayed.
