Here's what we know:
* Opportunistic feeding: Tiger sharks are known for their opportunistic feeding habits and will consume almost anything, including other sharks.
* Competition: In situations of limited food or overcrowding, competition for resources can lead to cannibalism.
* Size and aggression: Larger tiger sharks may prey on smaller individuals, especially juveniles.
* Rare but documented: There have been documented cases of tiger sharks consuming other tiger sharks.
It's important to note that cannibalism is not a primary food source for tiger sharks. They primarily feed on a wide range of prey, including fish, sea turtles, marine mammals, and even birds.
While cannibalism does occur in tiger sharks, it's not a frequent or widespread behavior. It's usually driven by factors like competition, size differences, or opportunistic feeding.
