New research off Cape Breton reveals that female pilot whales are the most frequent leaders during dives, often leading from the left or right flank, which could provide insights into mass strandings and help guide whales out of stranding situations more efficiently.

Rescuers were monitoring a pod of pilot whales swimming just off the northern tip of New Zealand's South Island late on Tuesday after more than a dozen of the group were killed in a mass stranding.

Nearly 100 pilot whales have died in a mass stranding on the Chatham Islands, New Zealand's Department of Conservation said Wednesday.

The seven northern bottlenose dolphins were spotted stranded on a beach in Rossnowlagh, County Donegal, on the north west coast of Ireland, earlier today.
