Marine Life

David Eynon first came to the Falkland Islands in 1970 as a travelling teacher.  He returned to England to take a degree and in 1974 married Carol Watson, who he had met in the Falklands. He worked in the North Sea from 1974 to 1981 diving commercially with Comex Diving out of Aberdeen.
 
Returning to the Falklands in 1981 with their children, they spent three months on a remote island searching for the wreck 'Conquimbana'.  They then got caught up in the war in 1982, and once stability had been restored, set up their company S.A.M.S. at their premises on the Stanley Harbour front known as The Boathouse in January 1985.
 
His passion for diving in the Falklands resulted in setting up the Wreck Survey Group, and more recently the Marine Exploration and Research Centre (M.E.R.C.).  Always enthusiastic about all matters relating to the marine environment, especially beneath the waters of the Falkland Islands he has produced two underwater videos, filmed for the BBC, and has now completed his first book. 

David’s Web site www.falklands-underwater.com gives more details about the work of MERC and other relevant information.
 
27p Sea anemone -  Bunodactis sp.
This white anemone is small, less than 5 cm across, and is found from the intertidal down to 20 m. It lives in rock crevices and also between mussels and is commonly seen with a red species, Bunodactis octoradiata. Little is known about the biology of this species and it is likely to be new to science.

50p –Jellyfish - Cyanea capillata
The Lion’s mane jellyfish is a large jellyfish with an umbrella diameter of usually 30 – 50 cm but has been recorded up to 200 cm. It is usually yellowish brown in colour and can be dark red underneath. Nothing is known about its life cycle around the Falkland Islands but data on populations in other parts of the world and anecdotal evidence from divers here would suggest that medusa (larval forms) are seen in the summer or early autumn with mature individuals more frequent in winter and early spring.

70p  – Starfish - Diplodontias singularis
The Biscuit starfish is brown to red in colouration and can grow up to 10 cm across. This species is found in the sublittoral and data from Falkland Islands Fisheries Department research cruises would suggest that it can be found as deep as 80 m. Diplodontias singularis is commonly found on rocky and sandy substrates in and around kelp (Macrocystis pyrifera) forests.

£1.15 – Nudibranch - Flabellina falklandica
The White tipped nudibranch is a small nudibranch (15 – 35 mm long) and it is either white/translucent to a pink salmon in colouration. Its cerata are coloured red or brown due to its digestive gland ducts shining though transparent tissue. It is found around most sub-Antarctic
Islands on rocky walls and on kelp species covered with hydrozoans. As with most of the other aeolid nudibranchs F. falklandica feeds on hydroids.
