Research indicates that various animals, such as killer whales and crows, exhibit behaviors that suggest they mourn the loss of companions.
A female killer whale named Tahlequah was observed pushing her dead calf's body, similar to a previous incident in 2018 where she did the same for 17 days.
Instances of animals, like elephants and chimpanzees, carrying deceased infants indicate a possible emotional response akin to grief.
Scientific studies reveal that animals undergo stress reactions and behavioral changes after losing a close companion, paralleling human experiences of grief.
Philosophical debates continue regarding whether these behaviors constitute true grief, with researchers suggesting a nuanced understanding of the emotional capabilities of animals.
