Yakushima - Wildlife of Japan

We observed this pair of Banded pipefish in Yakushima’s Isso bay. The pipefish have a white body with many reddish-brown horizontal stripes that cover it from the mouth to the tail fin. The gorgeous tail fin reminds me of the beautiful “Oiran” that Japanese high-ranking courtesans use.

The male banded pipefish has a pouch that incubates the eggs. There can be up to 100 eggs which hatch after about 10 days. The fries are about 6mm when they emerge.

Banded pipefish eat zooplankton. The entrance to this pair’s rock crevice was surrounded by little tiny fries and they were busy feeding on them.

We could see a pair of Harlequin ghost pipefish (Solenostomus paradoxus) in the seas around Yakushima. The pair were in perfect unison with their mimicry, which made it both astounding and beautiful to watch.

Harlequin ghost pipefish is a member of the family Solenostomidae. The Solenostomus were previously thought to be an intraspecific mutation within Solenostomidae but, they became an independent species in 1994.

On every part of the body and along its fins, there are spikes that stick out, with spotted patterns as well. The body is a white color with some transparent areas, but the designs and patterns that appear are so diverse!

The larger one is the female, and the smaller one on the right is the male. Unlike the pipefish, where the males incubate the eggs, in family Solenostomidae, they leave the job of protecting the fertilized eggs to the females with the larger pectoral fins.

In English, the name of the fish is “Harlequin ghost pipefish” or “Ornate ghost pipefish,” but in Japanese they are called “Nishiki fuurai-uo.” “Nishiki” refers to a traditional Japanese weaving textile, highlighting the intricate designs seen on this unique fish.
