Sharks of different species don’t necessarily hunt at the same time, scientists have found.
Researchers tagged 172 sharks — tigers, bulls, sandbars, blacktips, great hammerheads and scalloped hammerheads — in the Gulf of Mexico and tracked their movements.
It turned out that size does matter: Tigers, being the biggest sharks who also tend to kill smaller sharks, hunted whenever they felt like it, but usually during midday. All the other shark species hunted at other times, be it early in the morning, late afternoon or after dark.
