More than 600 sea lions have been found dead or dying on Peruvian beaches this year in the first mass mortality event of wild mammals from bird flu in South America.
A mass outbreak of avian flu among sea lions in Peru has revived fears the virus could be passing between mammals.
Since the start of the year, more than 600 sea lions (Otaria flavescens and Arctocephalus australis) have been found dead or dying on Peruvian beaches.
Six animals were tested for influenza and all tested positive.
