Seahorses are known to court their chosen one for several days, and they put much energy into this process. During the period of courtship, they will engage in what appears to be a sort of ‘love dance’. They swim side by side, mirroring each other’s movements; they swim snout to snout, hold tails and change colours to indicate that they are ready for romance.
Male seahorses, in what some women may perceive to be the ultimate romantic gesture, are the ones who fall pregnant and carry the young. The female stays by his side until he gives birth, and she will visit him regularly, continuing to hold his tail and flirt with him.
