The Harlequin Smiler, like all the aptly named jawfishes has a very large mouth. It occurs in tropical marine waters of the Western Central Pacific. In Australia it is known from central to southern Queensland.
The Harlequin Smiler is golden-yellow above and blue-purple below. There are blue-edged yellow spots on the sides and a deep blue blotch on the operculum. The dorsal fin has yellow stripes and the anal fin has yellow spots.
This species occurs over the sand bottom of the continental shelf. Mouthbrooders, the eggs of this fish are clumped together in a sticky ball inside the parent’s mouth. They are sometimes released in a burrow during brief feeding periods.
