The HMS Challenger Project Team visiting museums

Hello! Heather here. Recently Holly and I spent the week at the Natural History Museum in London. This is packed with specimens dredged and trawled by HMS Challenger – most departments will have some sitting in their store cupboards somewhere! NHM (previously the British Museum) took in all the types collected from the expedition before passing off some duplicates to many museums around the world (Sydney, Lisbon, Toronto, Berlin just to name a few of the international ones). They were left with well over 10,000 Challenger specimens. A couple of weeks ago we visited both the life sciences and the palaeontology departments looking at bottom sediments, ostracods, forams, dry corals, echinoderms and sea pens. We found a big starfish…

And then we found the sea pen. There was a particular sea pen we were wanting to find for a while. It didn’t come up on the NHM database search but we were determined that it was there somewhere! It is Umbellula thomsoni. It is in the class Anthozoa and the order Pennatulacea. The Umbellula genus was a rare zoological curiosity that was probably one of the first signs of deep-sea life and so it was a very exciting find for the Challenger crew! On top of it being rare, this particular specimen was an amazing example of bright phosphorescence exhibited in some marine life.  We are waiting for the specimen to be professionally photographed so I can’t show it to you yet but hopefully will be able to soon! Once back from NHM I had one week back in the office at RAMM and then disappeared off to the National Museum of Wales in Cardiff for 4 days to photograph some molluscs, including lots and lots of tiny shells! The majority of these were 6mm or smaller and so it was quite a fiddly job. We also got to photograph some bigger molluscs though – like octopus and squid.

Next stop is Dublin in 11 days time to visit the National Museum of Ireland. We are keeping busy here on the Challenger project!
