Diving with Ghost Pipefish

Koh Lanta Marine Life | Solenostomidae
CornetfishesSeamoths

Ghost pipefish are a member of a small group of tropical fish, a relative of the Seahorse, and can be seen at several sites while diving Koh Lanta.

With an elongated body and a long tubular head a third of their size. They are able to move their eyes separately enabling them to effectively scan their surroundings. Floating vertically, head-down, they suck up tiny invertebrate prey from the substrate using their distinctive tube-like mouth.

They do not have scales, like regular fish, instead they are encased in a series of tiny bony plates. Their tail fin is closed and they have two widely separated dorsal fins. Ghost pipefish are a monogamous species. The females are usually accompanied by a smaller male, she has an enlarged modified pelvic fin which forms a pouch for her to brood 300+ fertilised eggs.

Ornate (Harlequin) Ghost Pipefish

(Solenostomus paradoxus)

The ornate ghost pipefish or harlequin ghost pipefish is a very 'spikey', well camouflaged fish with many filaments on the body and jagged, deeply incised fins. This fish is actually quite common, but difficult to find. Once found however, it is very easy to identify due to its unique features.

The robust ghost pipefish can reach up to 17 cm and is the largest of the ghost pipefishes. Also known as the robust-snouted ghost pipefish or the squaretail ghost-pipefish, the body colour varies considerably, from red, yellow, brown, green and grey.

Robust ghost pipefish are uncommon and quite difficult fish to spot; they usually look like some drifting seagrass or bits of dead leaves. They float near motionless, with their mouths facing downwards, against a background that makes them nearly impossible to see.

This fish feeds on tiny crustaceans, sucked inside through their long tubular snouts.

Robust ghost pipefish live in open waters except during breeding periods, when they find a coral reef or muddy bottom, changing color and shape to minimize visibility.
