🌊Common seadragon
The common seadragon or weedy seadragon is a marine fish of the order Syngnathiformes, which also includes the similar pipefishes, seahorses, and trumpetfishes among other species. Adult common seadragons are a reddish colour, with yellow and purple striped markings; they have small, leaf-like appendages that resemble kelp or seaweed fronds, providing camouflage, as well as a number of short spines for protection. As with seahorses and the other syngnathids, the seadragon has a similarly tubular snout and a fused, toothless jaw into which it captures small invertebrate prey at lightning speed. Males have narrower bodies and are darker than females. Seadragons have a long dorsal fin along the back and small pectoral fins on either side of the neck, which provide balance. Weedy seadragons can reach 45 cm (18 in) in length.
