Seahorses are not vegetarians; they eat by hooking their tail around objects on the seafloor and use their snouts to snack on tiny, live crustaceans that float by. A tail that grasps objects is called a prehensile tail. You can see how the seahorse may have evolved into its unusual shape in the video above (courtesy of Nature). Even cooler: Did you know males seahorses carry and birth the young?
Many people don’t realize seahorses face many threats in the wild. You can help conserve these animals by refusing to buy them–either live, for your aquarium, or dried as souvenirs.
