A new study in Conservation Physiology, published by Oxford University Press, reveals that white shark activity increases dramatically when the animals are interacting with cage-diving operators.
In recent decades, wildlife tourism has rapidly expanded and is one of the fastest growing sectors of the tourism industry. Ecotourism opportunities to cage-dive with white sharks, large marine predators, are available in Australia, South Africa, the United States of America, Mexico, and New Zealand, with up to seven companies operating simultaneously in one site.
Previous studies have shown that wildlife tourism can change behavior of animal species by altering their habitats or eating patterns. How these changes affect the health of individual animals or animal populations is unclear.
The study shows that white sharks are more active and likely use more energy when interacting with tourism operators compared to other situations (e.g. when operators are absent), raising questions about the behavioral changes such tourism may be causing.
The researchers tracked ten white sharks at South Australia's Neptune Islands with devices for nine days, finding that the increased movement when sharks are interacting with cage-diving operators results in overall dynamic body acceleration, a proxy for activity, 61% higher compared to other times when sharks are present in the area.
[...] "Spending time interacting with cage-diving operators might distract sharks from normal behaviors such as foraging on natural, energy-rich prey like pinnipeds," Huveneers added.
[...] This study indicates that wildlife tourism may change the activity levels of white sharks and calls for an understanding of the frequency of shark-tourism interactions to appreciate the impact of ecotourism on this species fitness.

Fuck you.
These are some of the oldest-versioned, most streamlined killers on the planet.

Just... just... fuck off, already! You ruin being alive. YOU RUIN IT.
