Most wild seahorses are monogamous and some species mate for life. Searching for mates can be difficult and risky since seahorses are poor swimmers, found in low densities and rely on camouflage to hide from predators. By remaining faithful to one partner, the pairs have more time to undergo more pregnancies during a single mating season and, ultimately, have greater reproductive success. The pair-bonds of monogamous seahorses are reinforced by daily greetings.
