杂草seadragon（（phyllopteryx taeniolatus）是一种装饰精美的海洋鱼类，与海马和烟斗鱼有关。杂草的雪橇山是澳大利亚南部海岸的特有，被发现生活在海草床中，可以通过在海草叶之间漂移和摇摆来伪装。
成人杂草雪丝（Seadragons）可以达到45厘米的长度，并带有亮黄色的斑点和虹彩紫色条纹覆盖其身体的深红色颜色。在背面，杂草丝方的背鳍长，脖子的两侧都有较小的胸鳍，以保持平衡。
The weedy seadragon is covered in small appendages that looks like leaves or seagrass which it uses as camouflage, and is covered in tiny spines for protection. The weedy seadragons eat small zooplankton or tiny crustaceans they find amongst the seagrass.
Weedy seadragons are still uncommon in home aquarium however there are a few public aquariums in the USA have these magnificent animals on display. The Birch aquarium in San Diego has been成功的繁殖并将Weedys保持在囚禁中，并且是美国仅有的五个水族馆之一，在繁殖杂草雪松症方面已经成功。
像他们的海马表兄弟,男性杂草丛生的seadragonhave the task of carrying the eggs on their tails as the baby seadragons develop and until they hatch. The eggs still start out in the female however she lays about 120 of them onto the tail of the male when they are fertilizes.
杂草的雪绿色缺乏尾巴，海马用来将其挂在海草或珊瑚上，这就是为什么发现它们沿着海底漂流的原因。英国广播公司（BBC）的这段视频显示了一对崭露头角的Seadragons在浅海草床上跳舞。
