Many animals are able to detect magnetic fields, which can influence behaviours such as foraging, predator evasion and long-distance navigation. Some marine species including turtles, cetaceans and elasmobranchs use magnetic ridges on the sea floor as a navigational tool for large-scale migrations, particularly in pelagic areas where there may be a lack of visual or olfactory cues. Additionally, both aquatic and terrestrial species have been shown to align themselves on a north-south axis whilst resting, although the purpose of this behaviour is not fully understood. Numerous shark species are known to be highly sensitive to magnets in a variety of contexts and some have demonstrated the use of magnetic fields in long distance navigation, however little is known about the use of a magnetic sense for spatial orientation at smaller scales. Here we investigate resting magnetic alignment in Port Jackson sharks to better understand the use of this magnetic sense in the context of spatial ecology. Captive juvenile sharks housed in circular tanks were photographed at intervals over a 16-day period, and resting orientation was compared before and after the addition of rare earth magnets to the tanks. We expect this study to provide a better understanding of the mechanisms underlying spatial orientation in Port Jackson sharks and their ability to detect and use magnetic cues to orient themselves and navigate habitats over small spatial scales. It may also provide insight into how they navigate over longer distances during their annual migration.
