Mexican authorities have informed that dozens of dolphins were found stranded on a rocky beach along the coast of Baja California Sur State on Tuesday.
At least 21 dolphins were found dead out of the 54 that had washed up on the beach in northern Mexico, federal environmental protection agency said.
Workers attended to the dolphins and saved 33 of the short-beaked common dolphins, the Mexican environmental protection authority, Profepa, said in a statement.
The dolphins had bite marks that appeared to indicate they had been attacked by bottlenose dolphins, rescuers said.
An autopsy will be carried out on two of the animals for further analysis. Experts said it was the largest dolphin beaching incident seen in the state in recent years.
Photos released by the agency show dozens of dolphins washed up on the rocks and lined up in the sand, overseen by white-coated personnel.
Despite their cute and friendly reputation, some dolphins, including the bottlenose, are known to attack and even kill other dolphins.
