Ghost Pipefish - Solenostomidae
With their incredible ability to mimic their surroundings and their tiny size, it is not surprising that these spectacular critters are seldom spotted by divers.
Usually they are seen hovering next to their matching host, perfectly camouflaged. Their bodies are small and compressed, with large, often ornate fins. They can take on a wide variety of colours including red, white and yellow, depending on their surroundings.
Ghost Pipefish are also characterised by their hard body plates and tubular snouts, similar to the closely related seahorses.
