- Six species of large coastal sharks hunt in 'shifts,' according to a new study
- Bull sharks, one of the most dangerous, are most active in early morning hours
- Tiger sharks and sandbar sharks are active in midday and the afternoon
- Blacktip sharks are active during evening hours.
- Scalloped and great hammerhead sharks have 'substantial overlap,' with both species being most active at night
- It's unclear why they hunt at different times, but it could be to peacefully coexist
- 172 sharks were tagged with acceleration data loggers, used in smart devices
- In total, the researchers obtained 3,766 hours worth of data
