The ornate ghost pipefish (Solenostomus paradoxus), also known as the harlequin ghost pipefish, is one of the ocean's most breathtaking masters of camouflage. Characterised by a slender, compressed body adorned with elaborate, delicate cutaneous filaments and spike-like skin appendages, this species effortlessly blurs the boundary between animal and flora. Its elongated snout is trumpet-shaped, designed to vacuum up microscopic prey, while its large, ornate fins—particularly the wing-like pelvic fins and expansive dorsal fin—display intricate, kaleidoscopic patterns. The coloration of Solenostomus paradoxus is remarkably variable, ranging from translucent whites, vibrant yellows, and rich reds to deep blacks and mottled browns, typically studded with contrasting red, orange, and white spots. Females are notably larger than males and possess enlarged, fused pelvic fins that form a specialised ventral brood pouch used to incubate their eggs.

Ornate Ghost Pipefish (Solenostomus paradoxus) typically exhibit a solitary or pair-forming behaviour, often observed camouflaged amongst crinoids, hydroids, or soft corals, mimicking their host's appearance. They are generally slow-moving, using their unique morphology to blend seamlessly with their surroundings and ambush small invertebrates. Regarding reproduction, these pipefish are oviparous, with the female carrying the fertilised eggs. Instead of an external nest or broadcast spawning, the female possesses modified pelvic fins that form a brood pouch where the eggs are held and protected. The number of eggs carried can be substantial, although precise figures vary, ensuring a high reproductive output. Incubation occurs within this pouch until the eggs hatch into free-swimming, planktonic larvae. These larvae eventually settle and develop into their adult form. The species shows no defined seasonal reproductive peak across its wide distribution, with reproduction occurring year-round.
