Re: Vulture Catfish has black filaments protruding from body?

These look like epithelial projections that are prominent in some catfishes (e.g. in Bagrichthys and particularly Bagroides). If you look closely, the black projections are present right where the black spots are, and the pale projections are in places where the spots aren't.

Re: Finally mustered enough courage to pull the trigger

This book arrived for me via the museum at the same time that I received Francis Hamilton's Gangetic Fishes in Colour , though I have no idea why it was sent to me (I do not recall contributing to it in any way). Oh well, no point looking at a gift horse in the mouth. IMG_2066.JPG IMG_2067.JPEG I do...

Re: Finally mustered enough courage to pull the trigger

The Ray Society’s website is at https://www.raysociety.org.uk/ This is a completely new reprint that is far superior to the Junk reprint (which I also have). Membership is £10 per year. I cannot remember the members’ discount (I think it was at least 20%), but the Society has lowered the price of th...

Re: Finally mustered enough courage to pull the trigger

They are indeed. Putting this one on the Christmas list (it's not cheap as HH says). Here’s a tip: if you join the Ray Society (the folks who publish this), you get a sizable members’ discount if you purchase it through their website. The membership to the society is relatively cheap and the discou...

Re: Finally mustered enough courage to pull the trigger

I have no single favorite, but the drawings are exquisitely rendered, considering the circumstances under which they were executed. It’s also interesting to see the manuscript names written on the drawings (e.g. Pimelodus bagarius was originally named Silurus tigrinus ). AE811CB9-3FEC-4CD4-98FD-1ECA...

Finally mustered enough courage to pull the trigger

EA99EE91-DAF6-45CD-9447-C7D684EDDC69.jpeg
This came for me today, after I mustered enough courage (and funds) to pull the trigger.

I already have the Junk 1972 reprint of Hamilton (not the cheap, horrible Indian ones), but this absolutely blew me away.

Re: Feels good to be back in the lab

It would appear Dr. Ng is using an optical microscope and calipers to obtain biometrics of that candiru-like preserved fish in the plastic Petri dish. No? As to what the good doctor is doing yes. As to what fish it is, I can't tell. I was thinking of some kind of Ompok or other similarly shaped fis...
