What Are Some Predators of the Seahorse?

There are several predators of the seahorse, including the crab, stingray, tuna and penguin. Seahorses do not have a natural defense mechanism and they do not swim very well — two factors that leave them open to predation and reliant on their environment for protection.

The seahorse's size is one thing that helps to protect it because even the biggest seahorse measures a mere 8 inches in height, and the seahorse can change colors based on its environment, so it can stealthily hide from predators. Still, it is very susceptible to being eaten by other critters in the sea. Although a male seahorse can give birth to 1,500 seahorses or more at a time in pregnancies that last from 10 to 25 days, only 1 percent of the babies survive.
