A Different Kind of Dragon

20091101 RBJ 00028 (Medium)The leafy sea dragon (Phycodurus eques) is endemic to the waters of southern Australia and are closely related to seahorses and pipefish.  The leafy sea dragon is the South Australian Marine Emblem and they get their name from the leaf-like appendages on their bodies. They resemble pieces of seaweed, which makes them difficult for predators to find in their natural habitat of kelp and seaweed. Leafies are generally brown to yellow in body color with spectacular olive-tinted appendages. As an adult they can reach a total length of 35 centimetres.

The leafy sea dragon sucks up its prey using its long pipe-like snout and small mouth. Its    favourite food is mysid shrimps. Being slow moving, they rely heavily on camouflage for  survival, but also have long sharp spines along the side of the body. They are also able to change    colour to some degree. So much so that they blend in very well with their habitat. For novice divers Leafy sea dragons are extremely difficult to locate and many swim past thinking this majestic creature is just a piece of weed. With experience they are more easily spotted and once found are amazing to watch as their movements mimic the swaying kelp. They steer and turn by moving the tiny, transparent fins along the side of the head and move through the    water using the dorsal fins along the spine. Sea dragons have eyes that move independently of one another and the pattern around the eye is unique to each sea dragon. This pattern is used to identify individual animals.20050724 bluff 025 (Medium)

Unlike its relatives the sea horse, the leafy sea dragon is unable to coil or grasp things with its tail.

Unusually it is the male that gets pregnant and gives birth to live young. The female produces up to 250 bright pink eggs and then deposits them on to the male’s tail via a long tube. The eggs then attach themselves to a brood patch on the male’s tail, which supplies them with oxygen. It takes a total of nine weeks for the eggs to begin to hatch, depending on water conditions. The eggs turn a bright purple or orange over this period, after which the male pumps its tail until the infants emerge, a process which takes place over 24–48 hours. The male aids in the babies hatching by shaking his tail, and rubbing it against seaweed and rocks. Once born, the infant sea dragon is completely independent, eating small zooplankton until large enough to hunt mysids. Only around 5% of infants survive. Leafy sea dragons take about 28 months to reach sexual maturity.

The Leafy Sea Dragon generally reside in the same location for their entire life. Divers have recorded seeing the same animal in exactly the same place for many years. The male dragon may travel some distances however to disperse hatching infants to increase their chance of survival. They are then known to return to the same location after eggs have hatched. Often leafy sea dragons are found in mating pairs and it is widely thought that they mate with the same partner for life.

20091101 RBJ 00011 (Medium)Paul Macdonald is an Underwater Photographer with a passion for leafy sea dragons. He has been diving with them for over 20 years in his local South Australian waters. With his         considerable experience he is an expert at finding and photographing this magnificent marine animal. Diving regularly he is able to locate known individual dragons.

Paul says “It is important to have an intimate knowledge of the leafy sea dragon in order to photographically capture its beauty. They have a very unique behavior that needs to be   considered to create exceptional photographs.”

Paul regularly plans and leads dives for international photographers to capture leafy sea dragon images. He even shares his photography secrets to help divers capture the best      images.

He has an intimate knowledge of the local South Australian dive sites where leafy sea dragons are found. These dive sites such as Edithburgh, Victor Harbour and Rapid Bay are magnificent dive sites in their own right. And finding leafy sea dragons is the icing on the cake at these locations.

Paul is also available to photograph divers with leafy sea dragons to provide lasting memories of a wonderful diving experience.20110618 edithburgh_0002
