Hynobiid Salamanders (Hynobiidae) This group of Far Eastern salamanders are becoming increasingly popular in captivity, and thanks to the captive breeding efforts of one European hobbyist in particular (you know who I mean), they are becoming easier and easier to acquire.

It sure is Click the image to open in full size.

The purplish color, lack of dorsal patterning, and large size make it easily distinguishable from all other Japanese salamanders.

"The genus Pachypalaminus was originally erected for this species on the basis of its having a lacrimal bone in the skull, but it is now known that all Hynobius have a lacrimal bone, so there is no foundation for classifying it as anything other than Hynobius."

Source: Guide to the Amphibians and Reptiles of Japan (Goris & Maeda 2004)

They are said in the book to often prey on a large species of earthworm that grows to 16 cm in length.

In fact this one was reared as a larvae from eggs in Japan at temperatures of approx 20C... which I found incredible for a streamtype animal.

Well on this picture they do look skinny ,which offcourse has to do with the import. My nigrescens are having some spots still present after 2 years of age : the first 3 (all blue) is as they were but 1 year, the 4rd darker image is pretty recent :

Seems like you have adults, so mine will probably still darken up. But really the boulengeri is the giant among hynobius so you can not confuse them by their size.

Here's a new paper to keep an eye out for:

Biochemical phylogenetics and historical biogeography of Hynobius boulengeri and H. stejnegeri (Amphibian: Caudata) from the Kyushu region, Japan

By K. Nishikawa, M. Matsui and S. Tanabe.

Herpetologica. 61 (1):54-62. 2005.

Thanks, Paul.

Yeah, I love that luscious purple coloration. I reckon it'd taste like grape if eaten...Click the image to open in full size.

That picture was taken last year at the Japan Salamander Center in Mie Prefecture -- one of the few photos that survived the demise of my external hard drive. Thought I'd better post it here before I lose it too!
