*Abstract:*

Some aquatic mammals appear to care for their dead, whereas others abandon
their live offspring when conditions are unfavourable. This incredible
variety in behaviours suggests the importance of comparing and contrasting
mechanisms driving death-related behaviours among these species. We
reviewed 106 cases of aquatic mammals (81 cetaceans and 25 non-cetaceans)
reacting to a death event, and extrapolated ‘participant’ (*age class*,
*sex*, *relationship* and *decomposition*) and ‘social’ characteristics (
*escorting*, *calf dependence*, *alloparental care*, *herding* and *dispersal
patterns*) from published and unpublished literature. A multiple
correspondence analysis (MCA) was performed to explore the relationships
between these characteristics and death-related behaviours, with species
clustered based on MCA scores. Results showed that both cetaceans and
non-cetaceans react to death but in different ways. Non-cetaceans,
characterized by a short maternal investment, were observed to protect the
dead (defending it from external attacks), while cetaceans spent much
longer with their offspring and display carrying (hauling, spinning,
mouthing with the carcass and diving with it) and breathing-related
(lifting and sinking the carcass) activities with the dead generally in
association with other conspecifics. Our work emphasizes the need of
increased documentation of death-related cases around the world to improve
our understanding of aquatic mammals and their responses to death.
