Echinoderms (Echinodermata)

Echinoderms are represented in a number of collections of potential use for ocean acidification research:

  • Chagos Islands coral, Discovery and HMS Challenger collections at the Natural History Museum
  • Dry Invertebrate Store at the Zoology Museum, University of Cambridge
Heliopora coerulea, blue coral
Chagos Islands coral collections

The Chagos archipelago lacks overfishing and pollution, making it potentially suitable for use as a global reference baseline for monitoring the impact of ocean acidification on local biota. Although this is predominantly a coral collection, some other taxa are included. Find out more.


Formalin-preserved specimens from the extensive Antarctic Discovery expedition collections
Discovery collections

The Discovery collections originate from a number of different expeditions that took place from 1901-1999. The collection of pteropods may be of particular importance for ocean acidification research, and there are a wide variety of other marine specimens as well as ocean bottom deposits and residues.

HMS Challenger collection

Scientists on the 1872-76 HMS Challenger expedition collected a vast amount of natural history material from around the globe, which is accompanied by extensive taxonomic and summary reports. Get information about the Challenger collections housed at the Natural History Museum.
