Some aquatic mammals show varying behaviors regarding death, with some caring for their deceased and others abandoning live young under stress.
A review of 106 cases revealed distinct reactions between cetaceans and non-cetaceans related to death, highlighting different social and participant traits.
The study found that while non-cetaceans protect dead individuals, cetaceans engage in more complex behaviors, like interacting with and moving the carcasses among their group, indicating the need for further research on how these mammals cope with death.
