Gray Seals in Massachusetts (IMAGE) University of Vermont Caption The restoration of formerly endangered species is raising conflict in some places. One example: the return of gray seals to coastal Massachusetts. Here, gray seals (Halichoerus grypus) bicker at a sandy haulout in Chatham Harbor, Cape Cod during the summer of 2013. A new study by scientists at the University of Vermont and Duke University explores strategies to better manage and celebrate the recovery of these animals. Credit David W.
