Are sea snakes killing tiger sharks?

No, sea snakes are not routinely killing tiger sharks, but there is a hypothesis regarding an unusual interaction between them that might lead to shark fatalities. Wildlife biologist Forrest Galante explored the mysterious deaths of tiger sharks that washed up on beaches in Western Australia without any visible signs of injury or disease. His hypothesis was that these sharks might have been killed by sea snakes.

The scenario outlined involves a tiger shark consuming a sea snake, which, if bitten, could retalively bite the shark's inner mouth lining with its venomous fangs. While this seems like a highly unlikely event, akin to "winning the lottery" in its rarity, it is a possibility considering the nature of random events and sheer probabilities. This hypothesis was examined as part of an investigation to determine if it could be a viable explanation for the shark deaths 1 2.
