“…Visual health assessments using high resolution images of free-ranging cetaceans have proven to be an effective means to assess general health and body condition (Pettis et al 2004, Van Bressem et al, 2014a and occurrence and prevalence of barnacles (Kane et al, 2008). This methodology is also an effective means to examine the rate of anthropogenic scarring in cetacean populations, particularly those caused by vessel strikes (Moore et al, 2013;Hill et al, 2017, Bradford et al 2009, interaction with fishing gear (Robbins and Mattila, 2000;Neilson et al, 2009;Knowlton et al, 2012;Robbins, 2012;Basran et al, 2019), satellite tag insertion (Andrews et al 2019, Mizroch et al, 2010Robbins et al, 2013;Robbins et al, 2016), as well as predatory attempts by killer whales (Mehta, 2004;Naessig and Lanyon, 2004;Steiger et al, 2008;Capella et al, 2018).…”
