You are getting closer. Just curious what your P marleyi reference is? The pic I posted threw me off when I first saw it aswell compared to others I have seen.
@Zoodiver- that sucks,
@ Crumbs- My reference was a black and white drawing of them. Probably why I got it wrong. I can't find a photo of them anywhere.
So I think the last one in the genus is the leopard catshark (poroderma pantherinum)
Ive bin way to busy to research the genus but I have a feeling they you may have bin right serafino. The picture I posted was described as a Leopard Catshark- patherinum. However I think I said before the pic did throw me off because of the elongated barbells and coloration/pattern. A Leopard Catshark is at the start of this clip for reference. http://youtube.com/watch?v=7qggutehevQ
I dont have any other Leopard Catshark pics at this moment but I think they are visible at 53 seconds next to the Pyjama Cats in this vid. http://youtube.com/watch?v=i1B5F3645q0
Anyway heres a very easy one to ID to get this thread moving along.
Its an easy shark but I'm going to choose a funny angle maybe it will make it a bit harder.
The Fresno aquarium had a chance to get one of these but had to turn it down .
