Watch: Can humpback whales experience grief?

Watch: Can humpback whales experience grief? A study led by Griffith University and the Sea World Foundation indicates that humpback whale mothers may experience grief when their calves die. The research, described as uncommon, suggests these marine mammals could display mourning behaviors following the loss of their offspring. BBC's Tiffanie Turnbull explains the sighting off Australia's Gold Coast, outlining what observers need to know about the event and why such occurrences are considered truly rare.
