A team of marine biologists are investigating the mysterious mass stranding of orcas in Argentina, after 26 killer whales were found on the beach with no signs of injury or trauma.
Specialists at the National Scientific and Technical Research Council (CONICET) and the Southern Centre for Scientific Investigation (CADIC) were notified of two ecotype D orcas found in San Sebastián Bay, in the Tierra del Fuego province, in September.
