Australian scientists have discovered that sharks are not only hunters in the ocean, but also smart sea explorers who seek good luck and avoid evil. In order not to end up fishing in the back garden or to be attacked by more ferocious and larger sharks, different types of sharks will come for food at different times.
Scientists at Murdoch University in Australia have installed a small silent perception tracking device between 172 sharks and 6 different sharks.

The team has installed an accelerometer to measure acceleration in six species of sharks, including ferret shark (tiger shark), blackfin shark, bull shark, lead gray shark, hammerhead shark and Louis hammerhead shark. The Gulf of Mexico (accelerometer) helps track their movements, and eventually finds that sharks have no control over their movement and activity in this ocean area, but sharks of different species are seen taking a “turn”. Peak forging time will return within 24 hours. This is called “Deal Temporal Partitioning”.
Studies have found that bull sharks are most active in the morning and ferret sharks are most active in the afternoon, while lead gray sharks are most active in the afternoon, while black-striped sharks are mainly active at night, while hammerhead sharks are active only at midnight, while hammerhead sharks are also active.
When different species or groups of the same species live in the same habitat and use the same resources, resource allocation is now very important. To minimize competition, we will do our best to effectively divide common resources so that everyone can survive. Otherwise, vulnerable competitors may experience local extinction or develop new skills. Partitioning methods include food, space, or multiple time divisions.
Karisa Lear, PhD at the Center for Sustainable Water Ecosystems at Murdoch University, said: “As far as we know, this is the first example of a time-sharing hunt in the Marine Predator Group (same group). The team believes that the main reason for this hunt is to allocate resources, live together peacefully and protect themselves.
Time division can not only reduce food competition, but also prevent other large victims from being attacked, said PhD student Adrian Glies. “In fact, the time division may be related to the range.” Therefore, in order to avoid large sharks, fewer sharks will come out for food at appropriate times.
To humans, bull sharks, large white sharks, ferret sharks, and white-tipped sharks in the ocean are considered the four most dangerous sharks.
The team believes that the time-sharing hunting method of the leading prey will help maintain the balance of other marine life. Like trick-or-burn effects. The rules set by this group of superiors maintain a healthy and balanced habitat. It is hoped that the research will enable humans to better understand the ways in which these leading hunters share resources.
