Here's why:
* Bull sharks are found in coastal areas and estuaries, where sea otters also inhabit.
* Bull sharks have a wide diet, including fish, crustaceans, birds, and even other sharks.
* Sea otters are relatively small animals, making them potential prey for larger predators.
However, it's important to note that:
* Sea otters are agile and swift swimmers, which could make them difficult targets for bull sharks.
* Sea otters tend to stay close to the shoreline, while bull sharks are more likely to be found in deeper waters.
* Sea otters are highly social animals and often live in groups, which could deter individual bull sharks from attacking them.
Overall, while it's not impossible for a bull shark to eat a sea otter, it's unlikely to be a common occurrence. It's more probable that bull sharks would target larger, easier prey in their habitat.
