In water, the shark dominates. On land, the tiger wins. Environment determines everything.
This is the ultimate 'depends on the arena' matchup. In water, the great white is a 5,000-pound torpedo with 4,000 PSI bite force. On land, the Bengal tiger is a 600-pound apex predator and the shark is... a fish.
In shallow water where both can operate, this becomes genuinely interesting. The tiger is a decent swimmer and has killed prey in water before. The shark's ambush-from-below strategy is less effective in shallow water where the tiger can stand.
But the great white's raw size advantage (8:1 by weight) means even in shallow water, one clean bite could be catastrophic for the tiger.
8:1 weight advantage, devastating bite force, and complete aquatic superiority. Even in shallow water, the shark's mass and bite make it lethal.
The tiger is a capable swimmer with sharp claws and powerful jaws. On land, it wins automatically. In very shallow water, it has mobility advantages over the shark.
The shark wins in water; the tiger wins on land. We're giving a marginal edge to the shark because the size gap is so extreme that even in shallow water, the shark's bite is a potential one-hit kill.
