Great white sharks have long dominated the seas, however killer whales, which are reportedly bullying the great beasts and sometimes eating them, may challenge their authority underwater. The Farallon Islands, located off the San Francisco coast, are a critical base of research, where scientists monitor—among other things—13 different species of birds, five pinniped species, and great white sharks. It all started back in the late 1990s when a group of researchers made the annual trek to the Farallon Islands to observe the great white feeding season. A 2014 report of predatory activity at the Farallon Islands mentions a similar happening in 2009.
The connection between great whites and orcas has attracted the attention of many marine researchers. Despite the initial difference in methodology, all killer whale attacks on sharks include one vital element: flipping the shark upside down.
There has been a great deal of speculation as to why the killer whales have engaged in this kind of deadly bullying behavior, and some researchers suggest that it is not necessarily “new” behavior so much as it is newly observed behavior.
The vortex tail smashing wasn’t for a great white, it was observed that orcas did this to small mako sharks, much less sizeable than a great white. Some experts deplore the slaughter of sharks on the ground that they are needed to keep an ecological balance in the oceans. The American Museum of Natural History is committed to making its web site accessible to all visitors, including those with disabilities. The research on this phenomenon is not very extensive, but is showing some promising progress in the realm of understanding why killer whales have started attacking great whites.


The researchers studying the fierce predators arrive to the Farallon Islands in the summertime, when white sharks are known to frequent the area in order to feed on the abundant numbers of pinnipeds, or seals. They recorded the presence of killer whales in the area, which also feed on the pinnipeds, and thereafter witnessed a killer whale bully a great white.
Following a “depredation event” on a great white shark by a killer whale, the remaining white sharks left earlier than normal, as if bullied out of the area.
In western Australia, documentary makers are looking to experiment with killer whale audio to see if it will deter sharks in the immediate area. In some cases the whale rams the great white shark, effectively “stunning” it by catching it off-guard. This apparently induces what is called “tonic immobility,” an unlearned reflex that induces a trance-like stupor. Maybe it’s because they are aware of any humans swimming above them and just want to keep them protected. Some researchers are taking advantage of the opportunity to explore how this new breakthrough can help deflect sharks from coastal areas and popular beaches where high numbers of surfers and beachgoers congregate.
Researchers also observed a pod in the area this past fall, and wonder if that had anything to do with the lower-than-average number of shark predations on pinnipeds for the season. Researchers have over three hours worth of audio to work with, so they hope that in observing shark responses they can isolate the specific killer whale sounds that are the most effective shark repellants. In other more elaborate scenarios, the killer whales engage in what has been dubbed by one researcher, Dr. The killer whale continues to hold the shark down in this position causing it to suffocate, according to the reports. Generally orcas deter great whites by both their overall larger body size and the fact that they will attack the great white in groups.


So why not declare “open season” on those sharks known to be man-eaters, while focusing our efforts on protecting orcas from man-made pollution?
Ingrid Visser, as the “karate chop.” In this case, the killer whale produces a vortex by way of an “up-thrust of its tail” in the open water, forcing the shark up to the water’s surface. Regardless of the reason, some researchers are taking advantage of the opportunity to make beaches safer for beachgoers. Orcas generally attack sharks species that are far smaller than them, and the rarity of predatory observations on great whites suggest that orcas understand they would be very dangerous prey to tackle, particularly a large full grown great white. Therefore one can deduce that GWs have no fear of KWs and KWs dispatched the shark to eliminate a threat. When people are in trouble, dolphins are supposed to fight off sharks by using their high speed blows. At this point, the killer whale “pivots,” raises its caudal fin out of the water, and slams down with the entire force of its tail. Killer whale audio may prove to be a deterrent for great white sharks, although the effects and implications of faux whale calls on actual killer whales in the vicinity should be considered. The only known account of a one on one predation involved a juvenile shark of 10-12 feet long versus an adult orca about 16-20 feet long. I have to say that they are aware of the danger people are in because they think that we are on their team.
