* Larger Sharks: Great white sharks, bull sharks, tiger sharks, and even some smaller sharks like mako sharks can prey on dolphins, especially calves or weakened individuals.
* Orcas (Killer Whales): Orcas are the most common predator of dolphins. They are highly intelligent and social hunters, and can successfully hunt even adult dolphins.
* Other Marine Mammals: Large whales like sperm whales and pilot whales have been known to eat dolphins on occasion.
* Humans: Human activities like bycatch in fishing nets and habitat destruction contribute to dolphin mortality.
It's important to remember that these predators generally target sick, injured, or young dolphins. Healthy adult dolphins are rarely preyed upon by any other animals.
