Necropsies were performed on 3 of the pups at Adelaide University, but results were inconclusive, as the bodies were badly decomposed. Theories included infection or foul play.
The seals were found on a beach not too far from two large New Zealand fur seal rookeries, but there is no indication why the pups found their way there and why they died. It is highly unusual to have so many fur seals die in one place.
