I have been specialising in a group of marine bristleworms called magelonids for the last 17 years. Magelonids are known as shovelhead worms due to their distinctive spade-like heads that they use to dig in the soft sediments in which they live. Shovelhead worms have a world-wide distribution, generally living in shallow waters, although a few deep water species are known. I study the taxonomy of the group - a branch of science concerned with the classification of all living things, involving describing species, some which may be new to science. Principally I have worked on specimens from Europe, the Indian Ocean and the seas surrounding the Arabian Peninsula. However, more recently I have also been studying the behaviour of this fascinating group, investigating how they feed, burrow and move etc.

I was invited to colloborate with the University Museum of Bergen (UMB), Norway back in 2013 to work on shovelhead worms from Western Africa. The project, The Marine Invertebrates of Western Africa aims to investigate seabed samples from the West African continental shelf from Morocco to Angola. Very little is known about the shovelhead worms of this region, with only three species currently described, all from South Africa. Therefore I visited the lab at UMB to work with the team back in 2015 on MIWA material. The results from that trip were very exciting and approximately 20 different species of shovelhead worms were found in the material, many of which were likely to be new to science. Whilst work on these specimens carried on back at National Museum Cardiff, it was felt that it would be beneficial to re-vist Bergen to carry on the colloborative work. So consequently UMB invited me back to work with them once more this January. So for the last two weeks I have been studying more material from the region in order to find specimens for DNA analysis. DNA (Deoxyribonucleic acid) is found inside every cell of every living thing and is different in every individual. We can use DNA analysis to see the difference between very similar looking animals and thus we can see whether animals belong to the same or different species. We can then compare this information to what the species looks like (morphology). We have now selected 74 specimens which will be sent off for DNA sequencing and hopefully the results from that will come back shortly.

In the mean time work will begin on drawing, describing and imagining all the shovelhead worms from Western Africa. It is likely that there will be many new species within these samples, so we will need to decide on names for all of them and these will then be published in scientific papers. Once published this information will be used for example, by people monitoring the health of the seabed within this region.

One of the great things about being a museum curator is that I am always learning new things on the job. I have been a museum curator for 15 years.  In this time, my job has been to care for the mollusca collections but I have also now taken on the role of overseeing the care of the vertebrate collections. This has meant a whole raft of new things to learn and deal with, the least of which being that the animals all have backbones!

I was recently asked on behalf of the Sawfish Conservation Society (SCS) to investigate what sawfish rostra we have in our collections. So what is a sawfish? And what is a rostrum? Sawfish are incredible. They live in tropical and sub-tropical waters across the world. Also known as Carpenter sharks, they are in the same family as stingrays, electric rays and skates. Their characteristic feature is a long narrow nose extension called a rostrum which is lined with sharp teeth. These run down the length of the nose giving it the appearance of a saw.  To make this nose extension all the weirder, it is covered with electro sensitive pores that allow the sawfish to detect the smallest of movements on the sea floor. Little is known about the wild feeding strategies of sawfish, but it seems they skim the surface of the muddy sea floor looking for fish and crustacea, the way we might swish around a metal detector. The rostrum can be also be used to slash and impale anything that might be passing!

It is mostly due to this excellent nose that all sawfish species are listed as endangered or critically endangered. Seen as a curiosity, these sawfish rostra were prized by collectors. Overfishing and habitat destruction have had a devastating impact upon sawfish numbers, they have disappeared from at least 80-90% of the areas they once inhabited. They are now protected in a large number of countries making it illegal to harm them or trade in the removed saws.

The SCS has come up with a plan to help us better understand these amazing animals. They are partnering with researchers and institutes from around the world, which in the UK includes the Deep Aquarium and The Shark Trust, to launch the ‘See a Saw’ Citizen Science Sawfish Project.  Although the removal of saws has had a negative impact on their populations, researchers want to turn this negative into a positive. By using these saws to learn important information about them, they can then be used to conserve the remaining populations. They have the added bonus that the rostra are much easier to measure if the sawfish is not attached!

So with this in mind, I met with Al Reeve and his volunteer Sharon Williams from the South East Wales Biodiversity Records Centre (SEWBRec). Al is an avid elasmobranch enthusiast and it is through him that the enquiry first reached me. We set about photographing, measuring and counting the teeth of a whole series of rostra from the collections. It was an amazing experience to handle these specimens and to learn so much from Al about this group of animals. In the future, we may also be taking tissue samples from these rostra to send on to researchers for analysis. I quote Jeff Whitty, Founder and co-administrator of SCS to explain why:

"The data and tissue samples will be used in multiple international studies to further sawfish management and conservation. Sawfish have been suggested to be the most threatened shark or ray in the world and yet we know little about them, which makes conserving the remaining populations difficult. The morphometric data that you provided will help us improve our identification guides of sawfish and will provide us with a better understanding of the distributions of these species. The tissue samples from the rostra will be used by multiple genetic studies that are exploring the differences in the genetic diversity between historic and contemporary populations of various sawfish species. Information from these genetic studies will allow us to better understand if genetic diversity in current populations have declined or remained steady through the years and thus will inform managers if genetic health of a sawfish species or population is a topic of concern."

It is an unbelievably rewarding experience to know that this work can in a small way contribute to the conservation of this most endangered and enigmatic animal. We are often asked why we hold collections in museums. What good can come out of preserving animals? Why would we want to keep such a negative reminder of the wildlife that we have slaughtered on mass in our past? And we can answer that some good can come out of it. To conserve, to learn, to educate, to enthuse, and to help us do things better in the future. It is a great job that I am privileged to hold.

Yes, you have guessed it, it's time to roll out our annual #MuseumAdvent Calendar at National Museum Cardiff.

Each year throughout December we like to highlight our fantastic collections and spread some Christmassy cheer.

So why not find out what is behind each door of our advent calendar by following the @CardiffCurator Twitter account and see what wonderful suprises we have in store for you behind each one. We have delved deep into our collections to find some great Christmas objects. This year the theme of our advent calendar is lines from Christmas songs and poems. See if you can work out which song or poem each line comes from.

We have started off the calendar with:

Diwrnod 1 #AdfentAmgueddfa: ‘Aur, thus a myrr a gafodd ef, gan ddoethion ddaeth o bell’. Aur Cymru o gasgliadau @Museum_Cardiff

Day 1 of #MuseumAdvent - ‘Five gold rings!’, 5 nuggets of Welsh Gold from @Museum_Cardiff collections

Enjoy!

Update:

Well, now that the festive period is over and the decorations are coming down. We thought that we would put all of our Christmassy tweets together in this Storify for you to read.

The @CardiffCurator Twitter account tweets the latest news, research and events from the Natural Sciences Department at Amgueddfa Cymru - National Museum Wales. This can be anything from shells, insects, plants and fossils to minerals and birds. From specimens in our collections, to an insight of the research that happens every day just beyond the museum gallery walls. So what are our followers most interested in?

Here's a look back at the TOP TWEET and TOP MEDIA TWEET of each month during 2016 from the the account: TOP TWEETS 2016

Here at the Mary Gillham Archive Project hub we’ve recently begun ‘timehopping’ on social media.

This involves using Mary’s detailed writings to find out what she was doing on today’s date, so many years ago, and then posting it on Twitter and Facebook (i.e. “on this date, in this year, Mary was doing this…”). It’s an interesting way to learn about Mary’s life history and see the many activities that she got up to in her day-to-day life.

A recent and particularly intriguing timehop posted on 16^th October described how on that day in 1982, Mary witnessed the enormous humpback whale lying washed up on Gilestone beach at Aberthaw, near the Power Station.

This sparked the interest of many and after a twitter conversation with National Museum Cardiff it turns out that the bones of the whale are now on display at the museum, right here in Cardiff! This means that you can still visit this gigantic sea mammal today and see a part of Welsh history with your own eyes, just like Mary did.

Crowds on Aberthaw Beach

For those fortunate enough to be there in 1982 Aberthaw, the experience was an unforgettable one.

In her archive, Mary explains that it was almost “impossible to photograph the whale” due to the thousands of people congregating to get a glimpse.

The coastguard had tied the tail of the whale to a large iron post in the ground with ropes (to prevent the animal from washing back out to sea).

Mary describes how she got the chance to hold one of the whale’s gigantic flippers while Piers Langhalt, formerly of National Museum Cardiff, cut the large barnacles from the animal. These same barnacles can be found preserved at the museum, alongside the whale!

One volunteer on the Mary Gillham Archive Project, Julia Banks, recalls the “overpowering, rotting smell” of the beached whale that she witnessed as a young child. Julia visited the scene with her parents and remembers joining the masses of locals all gathering for the unusual sight, as well as seeing a group of people measuring the whale in order to figure out its age.

Julia also remembers visiting National Museum Cardiff when the skeleton was put up on display, and “feeling proud that [their] whale was in the museum”.

For more of the story and info on how the whale was managed by National Museum Cardiff, why not take a trip to the museum to see for yourself how it stands today?
