SHARK DIVE DEEP ON MOONLIT NIGHTS
The UWA - Science Alert
The Moon, water temperature and even time of day affect the diving behaviour of sharks, according to new research at The University of Western Australia.
A study of about 40 grey reef sharks - common on coral reefs in northern Australia and throughout the Indo-Pacific - found that the sharks stayed in deep waters on nights of a full Moon but rose to the night-time shallows with the new Moon.
Scientist said the research had conservation implications because sharks tended to congregate around reefs in many places across the Indo-Pacific and their diving behaviour might make them susceptible to being inadvertently caught by people fishing at different times of the day
