The sea dragon is an extremely interesting creature to learn about. There are three species of the sea dragon - leafy sea dragon, common sea dragon or weedy sea dragon, and ruby sea dragon. The scientific name of the leafy sea dragon is Phycodurus eques, which originates from two Latin words, namely, 'phyko' and 'oura', which mean 'seaweed' and 'tail' respectively. The latter part of the scientific name of the leafy sea dragon is 'eques' which means horse in Latin. Apart from the leafy sea dragon, there are two other species of sea dragon. The scientific name of the common sea dragon or weedy sea dragon is Phyllopteryx taeniolatus. The word Phyllopteryx has been derived from the words 'phyhllon' and 'pteryx' which means fin or wing. The Latin word 'taeniolar' is the origin of the word taeniolatus in the name of the weedy sea dragon. It means ribbons. Similarly, the scientific name of the ruby sea dragon is Phyllopteryx dewysea. This name is kept after the researcher Mary Dewy as a tribute to her love for the sea. The leafy sea dragon can change color to camouflage, however, all leafy sea dragons do not possess this ability. The ability to camouflage by changing colors depends a whole lot on the diet, habitat, age (generally above two years), stress, and other factors.

What is a Sea Dragon's habitat?

The sea dragon has a very restricted habitat. They can be seen only in tropical marine waters. They are native to Western Australia and South Australia. At times they can also be located in the waters of Tasmania. Sea dragons are not usually residents of deep waters however, they can travel as deep as 150 ft (46 m). They prefer to live in close vicinity to rocky reefs which are covered with kelps and seaweed. They can also be seen wandering near the grass-covered seabed or other phytoplankton and underwater plants. Their habitat consists of clear water. The temperature of the water should range somewhere between 54-73°F (12-23°C).

How long does a Sea Dragon live?

The average lifespan of sea dragons ranges from two to ten years.  

How do they reproduce?

Sea dragons attain maturity within the first two years of their lives. It is after attaining sexual maturity that a male sea dragon approaches females for mating. Although the exact mating ritual remains unknown, it is believed that the male sea dragon and female sea dragon form a pair, and they mate. At times males may fight each other over mating opportunities with a female sea dragon. During the process of reproduction, the females lay a clutch of on average 250 eggs. These pink eggs get fertilized once the females lay the eggs off on the tail of the males. The part of the tail where the eggs are attached is called the brood patch. The brood patch supplies oxygen so that the pink eggs can survive. Thus, the brood patch plays an important role in the reproduction process. It takes approximately nine weeks for the fertilized pink eggs to hatch. Until then it is the male who takes care of these eggs. For better care of the eggs, the male often pumps and may even shake his tail. Once the eggs hatch, independent baby sea dragons make their way into the world.

The overall conservation status of sea dragons is listed as Least Concern by the International Union for Conservation of Nature (IUCN) Red List. Both the leafy sea dragons and the common sea dragons or weedy sea dragons are listed by the IUCN Red List as Least Concern. Meanwhile, the conservation status of the ruby sea dragons is Data Deficient.

Sea Dragon Fun Facts

Little is known about the communication techniques of sea dragons. Sea dragons are known to have great camouflaging abilities, especially the leafy sea dragons (Phycodurus eques) with their leaf-like appendages. These leaf-like appendages look exactly like the leaves of surrounding plants which helps them to hide. By blending in with their environment, the sea dragons can escape their predators. They also float around freely in the water which makes them look like tiny bits of plants. This is also another way for them to not get preyed on.

The tail of a male leafy sea dragon changes its color to yellow when it is time for reproduction.

The sea dragons do not have any natural predators. The threats to their lives are mainly caused by humans. Human activities have led to the decline of their natural habitat. Human activities have also led rise to global warming which has changed the environment of the marine water bodies where they live. Apart from humans, sharks may also consume them at times making the sharks their occasional predators, and not natural predators.

The leafy seadragon is a tad bit larger than the other species. The leafy seadragon measures about 8-14 in (20-35 cm).
