A large, complete starfish has been discovered on the sands of Cockle Bight, just off Scolt Head Island. It matches perfectly the partial specimens recovered previously and can be confirmed as a new species, which I have tentatively named linumfenestra funiculus, the string thread starfish. Measuring 90cm in diameter, it confirms the speculation of a giant species of starfish living off coastal Norfolk.]]>anita.bruce@ntlworld.comThreadStars Blog2007-08-31T23:25:25+01:00http://www.anitabruce.co.uk/tblog/files/02257880df63b2d24747417753beb2bb-10.html#unique-entry-id-10http://www.anitabruce.co.uk/tblog/files/02257880df63b2d24747417753beb2bb-10.html#unique-entry-id-10Linumfenestra linus

This is an exciting discovery - although only part of the disc and arm remain, they are enough to suggest that the large disc and arm found earlier are linked, maybe even the same species.

A detailed analysis of the stitch pattern and thread will be carried out in the lab to see if the fragments are related.

I laid what seems to be the skeletonised limb of a very large starfish out on a nearby patch of sand, to make a cursory analysis. It appears to be a thread starfish, of a type unknown to me.

Field sketch of the starfish

Measurements:-
51cm in length
Tapers in width from 15cm to 3cm

Appearance:-
The tip is a circle with a 16mm looped border
Progressively wider semi-circles along the length, with a 16mm looped border increasing to 23mm
The skeleton appears to be made from a fine coarse white fibre

Further analysis of the thread and structure will need to be carried out in the lab.]]>anita.bruce@ntlworld.comThreadStars Blog2007-04-27T22:20:00+01:00http://www.anitabruce.co.uk/tblog/files/6bf027509090b9ed63430a536477f9aa-1.html#unique-entry-id-1http://www.anitabruce.co.uk/tblog/files/6bf027509090b9ed63430a536477f9aa-1.html#unique-entry-id-1

Today, I have made an exceptional discovery in a pile of sea weed and other detritus dragged high up the beach by the fierce tide. At first glance, it appeared to be just another dumped plastic bag, but closer exmination revealed something far more exciting - a patterned structure that seems to be made out of stitches and thread. Could this be part of the famed starfish that I've been searching for?]]>anita.bruce@ntlworld.comThreadStars Blog2007-01-03T12:00:00+00:00http://www.anitabruce.co.uk/tblog/files/348fdf792a7375aaafb8332d9ceea008-0.html#unique-entry-id-0http://www.anitabruce.co.uk/tblog/files/348fdf792a7375aaafb8332d9ceea008-0.html#unique-entry-id-0Unconfirmed reports talk of a giant starfish washed up during last year's spring leap tide somewhere along the shore of Scolt Head Island, the much studied sand spit on the North Norfolk Coast. The specimen has since disappeared, probably into the hands of a collector, but stories abound of the discovery of an intact starfish more than a metre and a half in diameter. Unlikely though it seems, this huge starfish may also be a member of the extremely localised Linumasteroidea species. So far, an appeal in the Eastern Daily Press to make the specimen available for scientific study has failed to reveal any traces of the specimen or further information about where it was found.

I have walked the length of the island whenever possible studying the tideline, a distance of some 6km, and always after the particularly high leap tides. I frequently find the more common species of starfish washed up, although what is now considered common in these days of turbulent changes in climate and the tropical sea conditions we now find off Norfolk, would have definitely been considered exotic until recently. The warmer, clearer waters and abundance of food on the newly formed coral reefs just offshore have certainly contributed to an increase in size in the starfish found and a 20 cm starfish is no longer a rarity, but a starfish this large seems an impossibility.]]>
