Why Are Seahorses Monogamous?

While monogamy is treasured in many cultures, does the same hold true in the animal kingdom? As it turns out, monogamy is not a particularly widespread practice. Seahorses are one significant exception.

Most seahorses are monogamous and mate for life. This is mainly because they are poor swimmers and have trouble finding mates. Hiding from predators is a full-time job for these creatures, so it’s no mystery as to why they choose to stick with a mate when they find one. Evidence also suggests that the longer a pair is together, the more successful they become at breeding, which in turn leads to more offspring.

Seahorse couples even engage in ritualistic dances. These moves can last from mere minutes up to hours on end and are utilized to strengthen a couple’s bond. This also helps to ensure that their reproductive cycles are synced.

Surprisingly, it is the male seahorse that actually gives birth to the young. The female deposits eggs into the male during mating, and the male carries them around until they are fully developed. As many as 1,000 babies can be born in a single birthing session.
