Wolves work together in the wild to ensure the survival of the rest of their pack, and this includes their elders. Whenever one wolf finds food, it will investigate it for edibility before calling out to the pack with a loud howl.
Older wolves lack the brute force in their jaws necessary to tear open the rubbery flesh of certain types of food. In this video, we witness younger wolves picking up most of the slack to ensure that their grandparents can feast on some of the softer meat of a washed-up sea lion.
After the younger wolves have had their fair share and removed most of the rubbery skin from the deceased animal, the older wolf swoops in to enjoy some of the softer meat inside. With most of the hard work already done, the older wolf is able to sustain its appetite and live another day.
