The “eyes” have it!

Seahorses and sight: Seahorse eyes do not work in unison like human eyes do, so these fish can actually see in two different directions at the same time. With eyes moving independently of each other (one looking in front, one looking behind), the animal has a full 360-degree picture of its surroundings! Because of their forward-facing position on the animal’s head, scientists believe that seahorse eyes enable binocular vision (which humans and many other species share). This type of vision is used to locate prey and assist with the small crustaceans that make up the bulk of their diet.
