Ghost pipefish are small fish that belong to the same order as seahorses and sea dragons.

They appear seasonally in shallow waters on coastal reefs and mucky sediments. Ghost pipefish are masters of disguise and divers get always excited finding these unusual fish.

Perfectly camouflaged they remain motionless and blend in well with their surroundings so that it is nearly impossible to find them.

It needs experienced eyes to beat their mimicry and knowledge of their preferred habitat to spot them amongst crinoids, sponges, coral or seagrass.

Ghost pipefishes grow to be about 10 to 15 centimeters long.

They have a short, laterally flattened body, which is not even 1 centimeter wide.

Their body is covered with small scales.

Several different species that mimic their respective environment and perfectly blend in.

Typical for the Harlequin ghost pipefish are the thorn-like skin appendages reminiscent of the feathers of feather stars.

The robust and delicate ghost pipefish, on the other hand, look like seaweed.

Coloring and appearance can vary widely within one species, between the sexes, as well as between adults and juveniles.



The family name Solenostomidae derives from the Latin solen = tube and stoma = mouth.
