From: Killer whales redistribute white shark foraging pressure on seals

Figure 3

The flight response of white sharks (Carcharodon carcharias) triggered by the presence of killer whales (Orcinus orca) at a common foraging site, Southeast Farallon Islands (SEFI). (A) Mean daily number of acoustic tagged C. carcharias detected (2007–2013; excluding 2009; shaded standard error) at Central California receivers colored by location: Tomales Point (green), Southeast Farallon Islands (orange and orange/yellow), Año Nuevo Island (blue), and Point Reyes (purple). (B) The number of tagged C. carcharias detected per day at each site (respectively colored) during the 2009 season showing the sudden departure of all tagged individuals from SEFI in response to O. orca (Nov 2) presence. Note the subsequent influx around Año Nuevo Island where the shaded orange area represents individuals present at SEFI during killer whale interactions. (C) Detections of each tagged shark at color-coded locations are shown along the horizontal timeline illustrating the abrupt departure from SEFI by tagged C. carcharias following O. orca presence (between vertical black lines) and subsequent avoidance. Solid orange diamonds indicate the western SEFI receiver while orange with yellow centers indicate the eastern receiver. (D) Precise receiver locations are indicated by the right corner of each solid diamond and the left corner of the yellow filled diamond.
