DragonetCallionymidae

Dragonets are bottom-dwelling marine fish, characterised by elongated, slightly flattened bodies and a broad head. Their large, upward-pointing eyes are set wide apart, aiding in spotting prey and predators from above. Most species measure 5 to 15 cm (2-6 in), with some reaching 30 cm (12 in). Their variable colouration typically provides camouflage, allowing them to blend with sandy, silty, or rubble substrates.

They inhabit areas often adjacent to coral reefs or within seagrass beds, from shallow waters down to 200 m (650 ft). Dragonets move with short, quick darts or by 'hopping' along the substrate using their pectoral and pelvic fins, preying on small benthic invertebrates. Males of many species feature an elaborately patterned and elevated first dorsal fin, which they display during courtship. Though common, their cryptic habits mean they are often overlooked by divers.
