Though it might not look like it, seahorses are actually fish and are closely related to pipefish and sea dragons. They do not have scales like most other fish but have bony plates below the skin that act like a suit of armor. Seahorses are weak swimmers, and their prehensile tail allows them to hold onto grass or rocks so they won't be swept away. Many seahorses can change color to camouflage with their surroundings; some species even develop fleshy tabs on their skin to help them hide. When eating, the seahorse's long snout acts like a powerful straw, sucking prey into its mouth.
