From: Assessing harbour porpoise carcasses potentially subjected to grey seal predation
Number of suspected grey seal predation and foxrelated cases of porpoises for the years 1990–2018; categorised by likelihood of grey seal predation (“likely”, “possible”, “unlikely”) and cases that were only observed but without recovery of the carcass (“observation only”).Cases related to fox interaction were included in the category “unlikely” and “possible” in terms of grey seal predation and are highlighted by a red square. The number is shown in brackets. The definite case is included as “likely” in this figure.
