My colleagues and I are analyzing predatory marks from killer whales to humpback whales in the southeastern Pacific and we have collected these images. Some have a clear identified marks such as rake marks (figure 7749), other are not obvious such as the flipper edges (Figure 9563, 8068, in red circles). Could someone answer me if these figures (9563, 8068) are evidence of killer whale predation on humpback whales?

Thanks
