Plocamopherus ceylonicus from northern NSW

From: Denis Riek


Dear Bill,
Here are two shots of Plocamopherus ceylonicus from the Brunswick River, nthn New South Wales, taken in February 2003. The upper photo is a form I have seen on several occasions and except for this one have all been very small juveniles. Both these animals were approx 25mm and were found in 3-4 metres on internal walls.

The lower photo is the typical colour variety here and shows how well it blends into its surroundings.
Regards,
Denis Riek.

Thanks Denis,
I've just included a closeup of part of your 'typical' colour form because if I had reduced the whole photo in size the animal would have been invisible. I'm afraid it's one of the problems with photographing 'camouflage' - If you take a good photo you can't see the object!

In the closeup you can see two of the brownish ball-shaped knobs on the end of the lateral papillae. These are one of the main sources of luminescence when the animal is agitated
Best wishes
