does laminaria digitata contain
Thank you for your enquiry. Dr John Bothwell (Leverhulme Research Fellow at the MBA) replies:
Sodium chloride (=NaCl) is made up of two different ions: sodium (Na+) and chloride (Cl-). In its solid form, these two ions stay bound together. However, when NaCl is put into water, the ions split from each other to give Na+ and Cl-. All living things contain Na+ and Cl- ions, including L. digitata. Those ions come, ultimately, from the seawater in which the kelps grow. So, yes, L. digitata contains sodium chloride, but so will any animal or plant.
I hope that is useful
P.s. Perhaps a web search for pages on marine algae and nutrition may indicate the levels of sodium chloride present.

To whomever it may concern. I am currently doing my 3rd year dissertation project at Bangor University on how climate change has effected the marine biodiversity around the UK and was wondering if there were any species which you thought this theory strongly applied to and what evidence there was to back this up. If you so desire, I can send you a copy of what I have researched so far.
Thank you for your enquiry.
As a first port-of-call you could look download our Marine Life Topic Note on Climate change from:
This considers climate change from the perspective of UK marine life and has some useful references.

me and my wife are huge fans of British rockpools where we can find all sorts of sea creatures, but we are short of information on where exactly we can find beach with rockpools in this country, is there any way we can get this kind of information? Our holiday sometimes are based on the this. Thanks!
Thank you for your email. The best areas for rockpools are in the west of England and Ireland, Wales and Scotland. Pembrokeshire, Devon and Cornwall are all particularly good as you can find warm and cool water species in the same place.
The Learning Zone of the MarLIN website is a good place to find information about UK seashore life. Visit:
The local Wildlife Trusts are a good source of local information once you have decided where you want to go!

while walking along the beach in Lincoln City, Oregon in the United States, my friend and I came across hundreds of these little round clear jelly spheres about the size of a marbel. While some were slightly larger or smaller, they were all basically the same size. They also seemed to have a sort of 'ribbed' texture with lines that appeared to run from top to bottom or side to side (depending on how you look at it). We held them above our flash lights and noticed that inside there seemed to be small white squigly lines, and in one case, a hint of red squigly lines. If you want to see a picture I posted pictures of a couple of them on my 'my space' page in my mobile photos. My name is Heather Templeton and my screen name appears as '(//_-) Lady' please feel free to take a look. I would like to know what they are. You can email me at firstname.lastname@example.org or you can message me over my space. I hope you respond. Thank you so much for your time.
Thank you for your enquiry. The little jelly spheres you saw are sea gooseberries, members of the Phylum Ctenophora. Sea gooseberries are carnivorous and can be found all around the world. See the MarLIN page for more information:

Hi, I'm leading NGO that deals with problems of biodiversity loss in Croatia. I'm organizing an event with children to celebrate World Water Day and Earth Day. I planned to have lessons on the beach, beach cleanup, games and quizzes... I'm new at this so would appreciate any help. If you could send me some materials, ideas or something...thanks
Thank you for your email. We have put together a guide for people who want to run seashore events for children. I attach a copy.
Also, you can download and print copies of the Seashore Code from our website:
www.marlin.ac.uk/learningzone/ and click on the limpet.
You can use the Seashore Code to talk to people about how to enjoy the seashore without damaging it. There are more resources on the Learning Zone part of the website such as species pages, topic notes on marine conservation issues and games and quizzes.
I hope these are useful and good luck with your event.

I've been referring to some of the species pictures in the species and habitats section (which are very useful!!). I think that the picture labelled 'Sagartia elegans var. minita on cobbles' is a photo of Cereus pedunculatus. Not intended as a critisim(!) - just noticed it and thought it might be worth mentioning. Brilliant and useful website - Thanks.
Thank you for letting us know. You are right it was incorrectly labelled. We have corrected this now. We always appreciate people noticing things like this on the website, and are pleased that you find the site useful.

Hi. Just a query. I believe the animals appearing in one of your images (P. maximus (faded red) and A. opercularis (beige shells) are in fact ALL Pecten maximus. I see that this image is credited to Keith Hiscock so I am not completely sure, but I am pretty darn sure. The beige shells are a view of the curved valve of this species that normally sits in the sediment (hence the colour difference).

Hi , I am a Primary 1 teacher in Renfrewshire and we will be doing a cross curricular project on "under the Sea" after Easter. I was wondering who to contact for more information? Thanks
Thank you for getting in touch about your school project. It sounds like a great project and I would be happy to offer some advice if I can. We do a lot of work with schools, including cross-curricular activities, linking science with art, literacy, drama, music, IT, numeracy etc.
I have prepared the attached guide for use by primary school teachers, specifically aimed at using the seashore to teach science. Although it is based around the English curriculum, hopefully it will give you some ideas that will be relevant for you. The guide is currently a draft, so if you have any comments, I would be very grateful!
If you are unable to visit the shore, some of the games and activities in the guide could be adapted for use in the classroom. I am also happy to suggest some other activities and projects. It would be helpful if you could let me know the areas of the curriculum that you would like to include, the ages of the children and if possible any visits you are planning to include and any resources you have available.
You may be interested to know that in the next couple of months, the MarLIN website (www.marlin.ac.uk) will be updated to include a range of new resources for teachers and we are in the process of preparing new resources to be included.
You may also find additional help and resources that are more local to you from the Scottish Association of Marine Science (SAMS) http://www.sams.ac.uk/education/schools.

I would be most grateful if you would supply me with a definitive macroscopic differentiation between the Common Smoothound and the Starry Smoothound
Dear Mr Mansfield,
I have been forwarded your email from MarLIN.
The only macroscopic difference between the two smoothhounds is their colouration. Whilst I would not usually recommend colouration as a means of differentiating between species, the starry smoothhound can be positively identified by the presence of small white spots over the back and sides.
Other differences between the two species include the dermal denticles on the shoulders (weakly ridged in the starry smoothhound and smooth in the smoothhound), the relative size of and distance between the nostrils (larger and closer together in the starry smoothhound) and the shape of the teeth (flat in the starry smoothhound but with weak cusps in the smoothhound) and tail fin (ventral lobe more pointed in the smoothhound).
I hope this helps!

Could you please recommend some Rockpool areas in the South Devon/Torquay region for seeing a good selection of marine species. Also, any possible Dolphin viewing areas?
Thank you for your enquiry. There are lots of great places for exploring marine life in Torbay. You could try Goodrington Sands and Babbacombe both of which have rockpools and seagrass beds.
Goodrington also has a seashore centre where you can find out more local information.
You could speak to the ranger at Berry Head visitor centre (details on the same website) about good dolphin spotting places.

We spotted a Lithodes maja in a rockpool at low tide on Tynemouth Longsands today (14/01/09). Is this common to find them in this region, and in a rockpool?
Many thanks for your sighting. An interesting species to find! There are reports of this species from northern Britain, but I do not have any records from Tynemouth. I attach our web page with some basic information on this species http://www.marlin.ac.uk/species/Lithodesmaia.htm and I have also cc'd Paul Clark at the NHM who I hope may have more information on its distribution and life history. As a northern species we are particularly interested in monitoring its distribution so I really appreciate this record.
Did you get a photo of the crab by any chance?
Thanks and I hope you will continue to submit records to our scheme.
