Intraspecific Interaction
Seahorse mostly interact with species of their kind. They communicate with one another by making a unique clicking sound that is produced when a structure called the coronet above their head grinds with another bone near by, and suddenly snaps. Seahorses are highly interactive when it comes to mating where males are either competing with other males for a female partner, or are having courtship.
Interspecific interactions
Seahorses do not interact much with other organisms unless they are hunting & competing for food, or are being attacked by a carnivorous predators such as sharks, rays, tuna fish, squids, and crabs .
