- Crabs: Crabs are one of the biggest predators of seahorses, and can easily crush their shells with their powerful claws.
- Fish: Many species of fish, including tuna, swordfish, and sharks, prey on seahorses.
- Birds: Birds of prey, such as hawks and eagles, can also snatch seahorses from the water's surface.
- Marine mammals: Some marine mammals, like seals and dolphins, have been known to eat seahorses.
