Sea snakes are a type of venomous snake that lives in warm tropical and subtropical waters. They are not typically found in the same areas as great white sharks, which prefer cooler waters. Additionally, sea snakes have a unique adaptation that allows them to absorb oxygen from the water through their skin. This means that they can stay underwater for extended periods of time, which would make them difficult for great white sharks to capture.
While it is possible that great white sharks may occasionally feed on sea snakes, it is not a common occurrence.
