" Predation on a White Shark (Carcharodon carcharias) by a Killer Whale (Orcinus orca) and a Possible Case of Competitive Displacement." Given the well-documented, predictable year-round presence of white sharks in Mossel Bay (Jewell et al., [7]; Ryklief et al., [13]), the sudden absence of white sharks for several weeks immediately after the predation event supports a flight response by surviving white sharks in the area.
