Common seadragons can reach 45 cm (18 in) in length.
Pipefishes or pipe-fishes (Syngnathinae) are a subfamily of small fishes, which, together with the seahorses and seadragons, form the family Syngnathidae.

The glassy sprat is a type of sprat fish. The fish, when alive, is translucent, so it gets the second word in its scientific name from the Latin word translucidus, meaning transparent, diaphanous. In animal classification the glassy sprat belongs to Osteichthyes, Clupeiformes, Clupeidae, Hyperlophus. The glassy sprat is native to Australia and mainly found in Australia. It is marked as NE because it has not yet been evaluated by the World Animal Protection. It is mainly used as an economical aquatic product. In ecosystems, they are at the bottom end of the food chain, feeding mainly on plankton, which are less aggressive and very vulnerable to other fish. Glassy sprat are tiny in size and translucent with a silvery streak that extends from its tail to just behind its head. As early as a hundred years ago, Australians harvested the glassy sprat in large quantities and it featured on the table as food for a long time. Due to its poor appearance, it is not a very good ornamental fish.
