The '''leafy seadragon''' (''Phycodurus eques'') or '''Glauert's seadragon''', is a marine [[Biology:Fish|fish]]. It is the only member of the genus '''''Phycodurus''''' in the family [[Biology:Syngnathidae|Syngnathidae]], which includes [[Biology:Phyllopteryx|seadragons]], [[Biology:Pipefish|pipefish]], and [[Biology:Seahorse|seahorse]]s.<ref>{{cite web |url= https://fishesofaustralia.net.au/home/genus/1160 |title= Phycodurus |last1= Gomon |first1= Martin F. |last2= Bray |first2= Dianne J. |date=n.d. |website=Fishes of Australia |publisher= Museums Victoria |access-date= 8 November 2022}}</ref>

[[File:Leafy seadragon skeleton 2019 1 8.jpg|thumb|Leafy seadragon skeleton]]
It is found along the southern and western coasts of [[Earth:Australia (continent)|Australia]]. The name is derived from their appearance, with long leaf-like protrusions coming from all over the body. These protrusions are not used for propulsion; they serve only as [[Biology:Camouflage|camouflage]]. The leafy seadragon propels itself by means of a pectoral fin on the ridge of its neck and a dorsal fin on its back closer to the tail end. These small fins are almost completely transparent and difficult to see as they undulate minutely to move the creature sedately through the water, completing the illusion of floating [[Biology:Seaweed|seaweed]].

Popularly known as "leafies", they are the marine emblem of the state of South Australia and a focus for local marine conservation.<ref name = "Yankalilla">{{cite web|url=http://www.yankalilla.sa.gov.au/webdata/resources/files/Leafy_Sea_Dragon_Information.pdf|title=The Leafy Sea Dragon|publisher=Yankalilla Visitor Information Centre|access-date= 17 August 2011 |archive-url=https://web.archive.org/web/20130509231926/http://yankalilla.sa.gov.au/webdata/resources/files/Leafy_Sea_Dragon_Information.pdf |archive-date=9 May 2013}}</ref><ref>{{cite web|url=http://animals.nationalgeographic.com/animals/fish/sea-dragon/?source=A-to-Z|archive-url=https://web.archive.org/web/20110520221952/http://animals.nationalgeographic.com/animals/fish/sea-dragon/?source=A-to-Z|url-status=dead|archive-date=20 May 2011|title=Animals: Leafy Sea Dragon |publisher=National Geographic |access-date=9 December 2011}}</ref>

== Description ==
Much like the [[Biology:Seahorse|seahorse]], the leafy seadragon's name is derived from its resemblance to another creature (in this case, the mythical [[Unsolved:Chinese dragon|dragon]]). While not large, they are slightly larger than most seahorses, growing to about {{convert|20|–|24|cm|in|round=0.5|abbr=on}}. They feed on [[Earth:Plankton|plankton]] and small [[Biology:Crustacean|crustacean]]s.

The lobes of skin that grow on the leafy seadragon provide [[Biology:Camouflage|camouflage]], giving it the appearance of seaweed.<ref>{{cite book |last= Cott |first= Hugh |date= 1940 |title= [[Biology:Adaptive Coloration in Animals|Adaptive Coloration in Animals]] |location= |publisher= Oxford University Press |pages= 341–342 |oclc=5232000}}</ref> It is able to maintain the illusion when swimming, appearing to move through the water like a piece of floating seaweed. It can also change colour to blend in, but this ability depends on the seadragon's diet, age, location, and stress level.

The leafy seadragon is related to the [[Biology:Pipefish|pipefish]] and belongs to the family [[Biology:Syngnathidae|Syngnathidae]], along with the seahorse. It differs from the seahorse in appearance, form of locomotion, and its inability to coil or grasp things with its tail.
A related species is the weedy seadragon, which is multicoloured and grows weed-like fins, but is smaller than the leafy seadragon. Another unique feature is the small, circular gill openings covering tufted gills, very unlike the crescent-shaped gill openings and ridged gills of most fish species.<ref>(Lourie 1999).</ref>

==Habitat and distribution==
[[File:Leafy Sea Dragon SA.jpg|thumb|At Rapid Bay jetty]]
The leafy seadragon is found only in southern Australian waters, from Wilson’s Promontory in Victoria at the eastern end of its range, westward to Jurien Bay,  {{convert|220|km|mi|abbr=on}} north of Perth in Western Australia.<ref name="iucn status 19 November 2021" /><ref name="Storrie">{{cite book|last=Morrison|first=Sue|author2=Storrie, Ann|title=Wonders of Western Waters|publisher=Department of Conservation and Land Management|location=Como, Western Australia|year=1999|pages=112|isbn=978-0-7309-6894-8}}</ref> Individuals were once thought to have very restricted ranges; but further research has discovered that seadragons actually travel several hundred metres from their habitual locations, returning to the same spot using a strong sense of direction. They are mostly found over sand patches in waters up to {{convert|50|m|ft|abbr=on}} deep, around kelp-covered rocks and clumps of sea grass.<ref name = "Yankalilla" /> They are commonly sighted by scuba divers near [[Place:Adelaide|Adelaide]] in South Australia, especially at Rapid Bay, Edithburgh, and Victor Harbor.<ref>{{cite web|url=http://www.uwphotographyguide.com/leafy-sea-dragon|title=Leafy sea dragon|publisher=Underwater Photography Guide Website}}</ref><ref>{{cite web|title=Victor Harbour (sic)|url=http://www.nevillecoleman.com.au/dive-travel-destinations--scuba-diving---snorkeling/australia-diving/south-australia/victor-harbour/ |archive-url=https://archive.today/20130202114543/http://www.nevillecoleman.com.au/dive-travel-destinations--scuba-diving---snorkeling/australia-diving/south-australia/victor-harbour/ |url-status=dead |archive-date=2 February 2013 |work=Underwater Australia |publisher=Neville Coleman |access-date=13 February 2013 |author=Neville Coleman |author2=Nigel Marsh }}</ref>

==Ecology==

Leafy seadragons usually live a solitary lifestyle. When the time comes, males court the females, they then pair up to breed. From the moment they hatch, leafy seadragons are completely independent. By the age of two, they are typically full grown and ready to breed.<ref name="NEAQ">{{cite web| author=New England Aquarium| title=Leafy Sea Dragon| publisher=New England Aquarium Animals and Exhibits| access-date=9 July 2013| url=http://www.neaq.org/animals_and_exhibits/animals/sea_dragons/| archive-url=https://web.archive.org/web/20130930143620/http://www.neaq.org/animals_and_exhibits/animals/sea_dragons/| archive-date=30 September 2013| url-status=dead| df=dmy-all}}</ref>

The species feeds by sucking up small crustaceans, such as [[Biology:Amphipoda|amphipods]] and [[Biology:Mysida|mysid shrimp]], [[Earth:Plankton|plankton]], and larval fish through its long, pipe-like snout.<ref name = "Yankalilla" />

===Reproduction===

As with seahorses, the male leafy seadragon cares for the eggs. The female produces up to 250 bright pink eggs, then deposits them onto the male's tail with her [[Biology:Ovipositor|ovipositor]], a long tube. The eggs then attach themselves to a brood patch, which supplies them with oxygen. After 9 weeks, the eggs begin to hatch, depending on water conditions. The eggs turn a ripe purple or orange over this period, after which the male pumps his tail until the young emerge, a process which takes place over 24–48 hours. The male aids the hatching of the eggs by shaking his tail, and rubbing it against seaweed and rocks. Once born, the young seadragon is completely independent, eating small [[Earth:Zooplankton|zooplankton]] until large enough to hunt mysids. Only about 5% of the eggs survive.<ref name = "Yankalilla" /> Each newborn fry begins life with a small, externally-attached yolk-sac. This sac provides them sustenance for their first few days of life. Despite this initial nutrition source, the majority of fry will instinctively learn to hunt and catch prey upon hatching, and will become self-reliant before the sac is gone.<ref>{{Cite journal|last=Groves|first=Paul|date=December 1998|title=Leafy Sea Dragons|url=http://dx.doi.org/10.1038/scientificamerican1298-84|journal=Scientific American|volume=279|issue=6|pages=84–89|doi=10.1038/scientificamerican1298-84|issn=0036-8733}}</ref>

===Movement===

The leafy seadragon uses the fins along the side of its head to allow it to steer and turn. However, its outer skin is fairly rigid, limiting mobility. Individual leafy seadragons have been observed remaining in one location for extended periods of time (up to 68 hours), but will sometimes move for lengthy periods. The tracking of one individual indicated it moved at up to {{convert|150|m|ft|abbr=on}} per hour.<ref>{{cite journal|last1=Connolly|first1= R. M.|last2=Melville|first2= A. J.|last3=Preston|first3= K.

==Conservation==

Leafy seadragons are subject to many threats, both natural and man-made. They are caught by collectors, and used in [[Medicine:Alternative medicine|alternative medicine]].{{citation needed|date=January 2022}} They are vulnerable when first born, and are slow swimmers, reducing their chance of escaping from a predator. Seadragons are sometimes washed ashore after storms.<ref>{{cite web|url=http://www.zooaquarium.org.au/Leafy-Seadragon/default.aspx|title=Zoo and Aquarium Association Inc|publisher=zooaquarium.org.au|access-date=8 August 2008|archive-url=https://web.archive.org/web/20110302022157/http://www.zooaquarium.org.au/Leafy-Seadragon/default.aspx|archive-date=2 March 2011|url-status=dead|df=dmy-all}}</ref>

The species has become endangered through pollution and industrial runoff, as well as collection for the aquarium trade. In response to these dangers, the species has been totally protected in South Australia since 1987, Victoria since at least 1995, and Western Australia since 1991. Additionally, the species' listing in the Australian government's ''Environment Protection and Biodiversity Conservation Act 1999'' means that the welfare of the species has to be considered as a part of any developmental project.<ref name="iucn status 19 November 2021" /><ref>{{cite web|title=Protected Aquatic and Priority Species|url=http://www.dpi.vic.gov.au/fisheries/about-fisheries/legislation-and-regulation/protected-aquatic-priority-species|publisher=Department of Environment and Primary Industries, Victoria, Australia|access-date=29 April 2013}}</ref><ref>{{cite web|title=ENVIRONMENT PROTECTION AND BIODIVERSITY CONSERVATION ACT 1999 - SECT 248|url=http://www.austlii.edu.au/au/legis/cth/consol_act/epabca1999588/s248.html|publisher=Australasian Legal Information Institute|access-date=29 April 2013}}</ref>

==In captivity==

Due to being protected by law, obtaining seadragons is often an expensive and difficult process as they must be from [[Biology:Captive breeding|captive bred]] stock, and exporters must prove their broodstock were caught before collecting restrictions went into effect, or that they had a license to collect seadragons. Seadragons have a specific level of protection under federal fisheries legislation as well as in most Australian states where they occur.<ref name="iucn status 19 November 2021" /> Seadragons are difficult to maintain in aquaria. Success in keeping them has been largely confined to the public aquarium sector, due to funding and knowledge that would not be available to the average enthusiast. Attempts to breed the leafy seadragon in [[Social:Captivity (animal)|captivity]] have so far been unsuccessful.<ref>{{cite journal|last1=Branshaw-Carlson|first1=Paula|title=Seadragon husbandry in the new millennium: Lessons learned from the past will create a sustainable future|journal=2012 International Aquarium Congress 9–14 September 2012|date=2012|url=http://www.iac2012.co.za/images/uploads/Seadragon_Husbandry_in_the_New_Millenium_-_Paula_Carlson.pdf|access-date=27 October 2014}}</ref>
