They exist I have seen them with my own eyes. The only thing that separated me from the most majestic creature on the celestial ball was about two inches of very thick plastic. I was in the presence of the most interesting, beautiful animal that has ever lived.

They are a lot like Sea Horses in the ways they bred. The males are pregnant instead of the women. (Goodness I wish I was a Sea Dragon.) They also have the long slender mouth that they use for feeding. Unlike Sea Horses their tails cannot be used for gripping, but why would they want to stay in one place when they can glide effortlessly through the water so that all may gaze upon their beauty.
There are only eight places in the United States that you are able to gauze upon the glory of these creates. The Shedd Aquarium, where I saw them, is one of these few places. If I were you I would get your buns over there and see these miracle. Sea Dragons like to be free and don't enjoy living in captivity. It is very hard to keep them in tanks. Attempts to bred them in captivity have failed. It is hard to obtain them because you can only own the ones bred in captivity. (I will however find a way to own one of these beauts someday.)
Leafy Sea Dragons are the coolest sea animal ever. There is no argument. I have seen them with my own eyes and even though they were a little blurry because of the tear (I might have started crying from the beauty) I could still tell that there is nothing that can compare to the shear awesomeness of these creatures.
