Millions of dead anchovies have been found on a northern Spanish beach, baffling experts who said they may have been chased into shallow waters by predator fish.
La Griega beach near the town of Colunga in the northern Spanish region of Asturias was thickly covered with dead fish on Friday.
"The most likely hypothesis is predators. Sea bass, dolphins or tunas might be chasing them too close to the shore," said Luis Laria, president of Spain's Marine Species Study and Protection Centre.
