Tag: Karimunjawa Dottyback (Pseudochromis ransonneti)

The Karimunjawa Dottyback (Pseudochromis ransonneti) is a small, elusive member of the Dottyback (Pseudochromidae) family occasionally found in local waters.

Although rarely seen, this species appears to favour shallow, silty locations which offer lots of protection from larger predators such as Mae Haad/Koh Ma off Koh Phangan and the local Koh Tao sites, although due to its small size (around 10cm) and elusive nature, it may be more common than the few encounters would suggest.

As members of this family often exhibit dramatic sexual dimorphism, it is possible that thus far, only the male or female has been identified in this section.

The following description of the Karimunjawa Dottyback assumes both male and female of this species share a similar physical appearance, which may be supported by their less frequently used "common name" of Yellowbelly Dottyback.

The main visual characteristics include the long slender body which is brownish/grey above and a striking yellow below.

There is a neon blue horizontal line both above and below the "tear-drop" shaped eye, with some small, indistinct blue markings just behind the eye.

The fins are predominately transparent, although there appears to be a blue/purplish margin on the dorsal fin of some individuals.
