Sand tiger sharks are relatively large sharks, with some individuals reaching lengths of over 10 feet (3 meters). They are also known to be quite aggressive and territorial, and are capable of defending themselves against predators. While great white sharks are larger and more powerful than sand tiger sharks, they typically target weaker or smaller prey.
In some cases, great white sharks may attack sand tiger sharks as a form of competition for food or territory. However, these interactions are relatively rare, and sand tiger sharks are not considered to be a significant part of the great white shark's diet.
