According to the Mexican authorities, dozens of dolphins have been found stranded on a rocky beach along the coast of Baja California Sur state.
The federal environmental protection agency said that 54 of the marine mammals came onshore in the area of La Paz Bay. Workers attended to the dolphins and saved 33 of them, but 21 died.
On Tuesday, the agency in a statement said that they were short-beaked common dolphins.
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.
