Alabama (AL) is a hotspot in the Gulf of Mexico (GoM) for human interaction-related cetacean strandings, including harassment, vessel strikes, and fisheries interactions. We examined four bottlenose dolphins () stranded dead along the AL coast during 2012-2017 with severed peduncles suspected to be related to human interaction (HI). Evidence from each case, including photographs, gross necropsy results, and histopathologic findings when available, was reviewed to determine the mode of severance and whether it contributed to death.

A total of 1,887 postmortem reports (1965-2018) collected from more than 150 institutions were reviewed. Histologic findings from 862 postmortem reports and primary causes of mortality were compiled to determine the most common findings.

One manatee also had an undifferentiated sarcoma that may have arisen from the histiocytic sarcoma.
