With a very long thin snout and a slender trunk covered in bony, brightly colored rings, common seadragons differ from seahorses in that their thin tails cannot be used for gripping. Therefore, they are oftentimes found happily drifting along with the current like a piece of seaweed. Weedy seadragons are usually reddish brown in color with yellow spots. Their most unique feature is the small leaf-like appendages growing out from their body that resemble seaweed and help them to camouflage well. Unlike its cousin the seahorse, which is fairly widely distributed, it is endemic to Australia and is only found along the southern shores of Australia where the Eastern Indian, Southern, and Southwestern Pacific Oceans meet.
