DENPASAR, Indonesia — Lung damage, hunger and disorientation have been cited as the factors that led a pod of 52 pilot whales to a mass stranding on an Indonesian island earlier this year.

The experts said the cause of death of the alpha pilot whale, a female, was shortness of breath caused by damaged air sacs in her lungs, and hunger. Dehydration and exhaustion were found to be the cause of death for the rest of the pod. They also found severe inflammation in the alpha whale’s melon, which most likely disrupted her ability to navigate and subsequently led her and the rest of the pod to wash ashore. Pilot whales are very social animals that travel in groups. “This colony was traveling in a triangle form with the youngest at the back.
