Here's why:
* Dugongs are herbivores: They primarily feed on seagrass, which is not a typical part of a Great White's diet.
* Habitat overlap: While there is some habitat overlap between Great Whites and dugongs, they are not commonly found in the same areas.
* Defense mechanisms: Dugongs have a thick layer of blubber and a strong tail, which could make them difficult for Great Whites to kill and consume.
However:
* It's possible that a Great White might scavenge a dead dugong or even attack one if it was injured or in a vulnerable state.
* Some studies suggest that Great White sharks might be opportunistic feeders and could potentially prey on dugongs in rare cases.
Overall:
While there's no definitive evidence of Great Whites regularly hunting dugongs, the possibility remains open, especially in situations where the shark is desperate for food or encounters a weakened dugong.
