An unusual discovery has been made at Purbeck’s Arne Nature Reserve. What was originally thought to be a small toy was found to be the remains of a real seahorse. Short-snouted and Spiny seahorse are known to be inhabitants of Poole Harbour and the surrounding areas, but it isn’t often they appear on the shores of Shipstall Beach. A short-snouted seahorse, the less common of the two species relative to the British Isles, was spotted by a walker before being passed onto RSPB volunteer and wildlife enthusiast, Graham Tarrant.
His son and fiancé, both marine biologists, were visiting for Christmas and suggested doing something with the seahorse rather than bury it. The inital plan to contact the Dorset Wildlife Trust, for which Graham is a member of, failed as they had closed for Christmas. It was then that Neil Garrick-Maidment of The Seahorse Trust was contacted.
“Polly, my future daughter-in-law emailed Neil to find out what we could do with it. There was a great debate whether to freeze it or pickle it”, Graham said. “I still remember from my A Level in Zoology that we put everything in Formalin to preserve it. Surgical spirit was the purest alcohol we could think of that we could easily get hold of, apart from vodka but that seemed a waste.”
Before it was stored in the alcohol, Graham took photographs of the creature to send to The Seahorse Trust, in advance. The images show it was a small, male seahorse just under 8cm. Although it was not pregnant at the time it is thought that it may have previously been.
Graham travelled, just after New Year, from Wareham to Ottery St Mary, where The Seahorse Trust is based. Putting it in the spirit, as opposed to freezing it, meant it is possible to still retrieve its DNA. Research can be carried out and DNA testing on enough samples could indicate some idea of population size for a certain area.
Although a rare occasion, this isn’t the first seahorse to be washed up in Dorset. In 2010 a number of spiny seahorse appeared on the shores of Hamworthy.
