This pipefish species is brown in colour, usually with whitish mottling which allows it to camouflage amongst dead Posidonia seagrass. It is named for the long rounded ridge on top of its head. This is a distinctive feature, albeit one shared with its close relative, Histiogamphelus cristata. The primary differences between these two species are the longer snount of H. briggsii, and its ridge or crest, which does not extend farther back than its eyes.
