The article focuses on research published in the April 2019 issue of "Scientific Reports" concerning great white shark behavior off of the Farallon Islands in California. It states researchers found in 2009 17 tagged white sharks that had been simultaneously swimming in the area abruptly departed in a matter of hours due to the presence of orcas. It comments on orca feeding habits with orcas competing with sharks for seals and occasionally eating sharks.

Abstract: This article reports on the first comparative surveys in two separate locations to measure public attitudes toward sharks following shark bite incidents. This study focuses directly on the communities affected by the shark bites, both in Australia—the town of Ballina in the State of New South Wales (N = 500) and the city of Perth in Western Australia (N = 600)—and reports on their attitudes and policy preferences relating to sharks immediately after serious shark bite incidents in 2015 and 2016. In both communities we find that a large majority of respondents prefer nonlethal policies; most respondents believe shark bite incidents to be accidental rather than intentional; while fear of sharks correlates with support for lethal policies, this association is powerfully mediated by perceptions of intentionality. These findings have implications for international wildlife management, particularly regarding predator species in need of conservation. Conservation is based on the public acceptability of a species and if intentionality can mediate fear effects and promote policies that protect the species this is a step forward for conservation management globally.

This piece is dated, but may contain useful keywords: "Three symbols of terror are examined as representations of preoedipal conflicts that intrude upon conscious awareness and. interfere with current functioning. To understand each of these symbols and their origins in a state of chronic terror, it is necessary to understand the complete life history of the patient. All three symbols--the witch/vampire, the spider, and the shark--relate to earliest experiences within the parent/infant dyad. We suggest that although all three symbols relate to the dimension of oral aggression, they can be placed conceptually along a continuum of distance from the quality of humanness. Clinical examples are given to illustrate the use of these symbols by patients in treatment and their theoretical implications." (PsycINFO Database Record (c) 2016 APA, all rights reserved)
