Twenty-one of fifty-four seemingly attacked dolphins that washed up on the shore of a Baja California Sur beach have died.
Rescuers and the Ministry of the Environment saved 33 of the dolphins.
Authorities are still unsure as to why so many short-beaked species of dolphins ended up on the rocky shoreline in the first place, but by the looks of the bite marks all over their bodies, scientists suspect they were attacked by omnivorous bottlenose dolphins.
"The whole beach was filled with dolphins. Little by little, we pushed them back into the water in groups of two or three so they could swim out in groups," said a volunteer and marine biology student, Maria Jose Amador.
Officials will conduct autopsies on the 21 dead mammals to better understand their cause of death.
