Hundreds of dead starfish wash up on Talybont beach
Several hundred dead starfish have been found washed up on a north Wales beach.
It comes following the discovery at Talybont, between Harlech and Barmouth in Gwynedd.
Council maritime officer Barry Davies said it is common for starfish to be washed ashore during spring tides but it was not clear why they had migrated so far up the shoreline.
Barmouth harbour committee chairman said an inquiry is needed.
Councillor Trefor Roberts said: "What I would like is a full scientist report on what caused the deaths of these starfish."
Mr Davies said he did not think anything suspicious has led to the deaths of the starfish.
He said that the common starfish - found around the UK coast - feed on mussels and other crustaceans and while there is no clear reason why the starfish migrated so far along the coast he felt one reason could be a shortage of food.
"We are confident that the cause is not related to pollution or to a vessel having dredged the starfish and discarded the starfish overboard," he said.
Although a distressing sight to see, he said the starfish were not a hazard and would probably be consumed by seagulls.
Talybont resident David Haddon said: "I can understand one or two dying, but there have been occasions where loads of jellyfish have died in this area."
