Marine Mammal Stranding


The Division will respond to reports of stranded marine mammals. Once on scene, the responding officers will assess the animal and then contact the appropriate authorities.

The Division works very closely with the Cape Cod Stranding Network who has the authority and expertise required to handle marine mammals. We will monitor the animal and create a safety zone around it while awaiting the stranding network.
