Cnidaria collections
A hydrozoan specimen © The Trustees of the Natural History Museum, London
The cnidaria collections include corals, jellyfish, sea anemones, octocorals and hydroids, with approximately 20% of the specimens known to be types.
The geographical strength of the collection is our Indo-Pacific holdings, particularly material from the Red Sea, Arabian Gulf, Chagos Archipelago, Maldives, Malaysia, Singapore and Australia.
Other geographic highlights include Atlantic and Antarctic material. A largely historic collection, the non-reef corals are from important deep-sea expeditions such as the Challenger Expedition, the Discovery Expeditions and the John Murray Expedition.
We also care for the types and other specimens figured in the seven volumes of the Catalogue of Madreporaria (1893-1928) compiled by George Matthai, Cyril Crossland, J. Stanley Gardiner and J.J. Lister.
The Natural History Museum cnidaria collection is used for taxonomic research, studies of coral richness (species, generic, morphological, genetic), as well as for understanding time series trends in ocean acidification and for climate change research.
