It turns out that when the moon fills, more sharks attack humans

It is widely known that the phases of the moon cause the ebb and flow of the tide, and it has been pointed out that it may be related to human sleep time, and it is whispered to be related to many events on the earth. Meanwhile, a shocking research result was reported that 'when the moon fills, the number of sharks that attack humans increases.'

Under a Moon Spell: Shark Attacks Related to Lunar Phases

The link between the phases of the moon and human attacks by sharks was reported by a research team led by Lindsey French, who participates in the University of Florida's shark research program. The research team collects information on shark attacks from around the world for 50 years and analyzes the relationship between the illuminance of the moon and the number of shark attacks. As a result, it became clear that the number of attacks was higher on days with high moon illumination (full moon) than on days with low illumination (missing moon).

This study does not show why the phases of the moon affect shark behavior. However, one member of the research team, Stephen Midway, said, 'Most of the shark attacks occur during the day, but the moon can have a very small impact on the Earth's land and sea. We support the possibility that the moon has some influence on shark behavior.

On the other hand, Midway also states that there is not enough information to determine that the phases of the moon are affecting the shark attack. In addition, Science Alert, a scientific media, showed the results of past (PDF file) research that 'more people enjoy surfing in the full moon and more attacks by sharks', and changes in human behavior caused an increase in the number of attacks. I have pointed out the possibility that it is.
