Why is the whale 'grieving'?

Whales can exhibit behaviors that appear to be grief when they lose a companion, such as another whale or a calf. This may include staying close to the deceased, vocalizations, and changes in behavior that suggest distress. The phenomenon is often attributed to their strong social bonds and emotional intelligence, leading them to mourn like many other animal species. Such behaviors highlight the deep connections and complex emotional lives of these marine mammals.
