It is a small marine fish of the seahorse genus in the family Hippocampus. Usually living in tropical and subtropical coral reef areas, it is known for its unique appearance and behavior. The body is horse shaped, with a pair of big eyes on the head and a curled tail that can firmly grasp seaweed or seaweed, thus maintaining stability in the water flow. Their body length is generally around 15 centimeters, and their body color varies from yellow, orange to red, sometimes with black or white stripes. This protective color helps them hide in the underwater environment. It is a species where males become pregnant, and females lay eggs in the male's brood sac, which is then incubated and protected by the male until the birth of a small seahorse.
