Do Animals Understand Death?

Do animals understand death? A mother sea otter carries her dead pup for over a week, refusing to let it sink. A lone goose abandons its flock and wanders back to places it used to go with its partner. A mother giraffe stands over her dead calf for three days in open predator territory, chasing away hyenas, not eating, barely moving. And in 2014, a group of twenty sperm whales arranged themselves in a silent circle around a dead juvenile in the middle of the Atlantic Ocean and held position for hours. These aren't isolated incidents. They're happening across dozens of species. And scientists still can't agree on what any of it means. In this video we look at what animal behavior around death actually tells us, where the science is settled, where it genuinely isn't, and why the question itself might be harder than it first appears. 0:00 - The sperm whale vigil 1:34 - Sea otters and grief 2:28 - Geese and mourning 3:41 - The giraffe that stayed for three days 4:42 - Why studying animal cognition is hard 5:34 - Western scrub jays 7:21 - Bees and preprogrammed behaviours 8:19 - Are we asking the wrong question entirely?
