These marine fish are called sea dragons, they are related to the seahorse and they are really cute. There are two types of the sea dragon: the leafy and the weedy sea dragons. They normally can be found along the southern and western coasts of Australia. The leaf-like protrusions coming from all over the body of leafy sea dragons and the weed-like projections on the body of weedy sea dragons serve them only for camouflage and not for propulsion as one might think.
