Here's why:
* Size: Polar bears are the largest land predators, and their size directly contributes to their larger teeth.
* Canine Length: Polar bear canines can reach lengths of over 4 inches, while tiger canines are typically around 3 inches.
* Evolutionary Adaptation: Polar bears' canines are specifically adapted for hunting seals, requiring powerful tearing and piercing abilities.
So, while tigers are formidable predators with large canines, the polar bear takes the crown for the largest canine teeth among all canines.
