Seahorses have a very intimate courtship. They hold tails, swim snout to snout and engage in a courtship dance. Once the male seahorse is pregnant—yes, the male carries the eggs to term—the female visits him every morning and holds his tail. Seahorses have monogamous relationships, and the male cares for the unhatched eggs, regulating the conditions inside the pouch where the eggs are stored.

This seahorse’s small size allows it to explore even the slimmest crevices of reefs, where it searches for food and finds coral pieces on which to anchor for rest and protection.

Both males and females are typically a yellow color, with flecks of brown and black, allowing them to blend into their reef habitats. This camouflage coloration, along with their bony body, allows the longsnout seahorse to have very few predators.
