What is that?

[Amberdawn]

Hi

Does anybody know what type of ancistrus is on the homepage of "All Catfish Species Inventory"? Its the drawing on the top right hand corner just above "participant log in" It has bristles that fan out at the ends, not typical forks, but a fanned out brush on stalks.

I saw a photo on some forum (don't remember where, drat) of a LF brown bristle nose that had tentacles just like that. I thought it was merely some odd sport, and then I saw that drawing, so I figure some species of Ancistrus somewhere must actually look like that. One of the "Ls" that doesn't have a photo in "Cat-e-log"????

Here's the drawing, for reference......


It does say Ancistrus.

Yes, that's the drawing, thank you for putting it up!

I did know it's an ancistrus, but which one, what "L" number or species, is what I was wondering if anyone knew.

I think that would be a question best put to the ACSI - I doubt that it is an L-number, because ACSI doesn't do L-numbers. They may have undescribed species in their lists, but they would not use the "amateur" L-number system.

My guess is that the picture is actually from some original description of one of the old species of Ancistrus.

Hi,

looks to be one of the drawings of Ancistrus eustictus (Fowler, 1945).

Cheers, Sandor

Thank you all for your replies.

A eustictus was indeed one of the Cat-e-log species that did not have a picture. I realize no photo is available, I googled the species and nobody had pictures. I also realize that generally one Ancistrus species looks pretty much like another, which is why they can be so difficult to identify, but with one like this that has a distinctive characteristic like the tentacle form of this fish, wouldn't posting that drawing on Cat-e-log be better than nothing?

I'm sure if we could have permission from the original author to publish the photo, we would do so. I'm not entirely sure that it's easy to get that. I'm sure ACSI is getting away with it using the "quote" rule of copyright (you are allowed to use portions of a document/picture as a quote to make another document or image). We would not be able to use that, as we are distinctly copying the image as it's value as an image on it's own.

I wonder if Mike Noren has access to the specimen NRM 15146 and perhaps could get us a photo?

The region of Colombia that this fish comes from is not the typical region for export.

Link to collection record.

Unfortunately, no image listed.

Similar perhaps to

Ancistrus stigmaticus

(?)

Hi Everyone,

I looked at a photo of A stigmaticus and it does have thick different looking tentacles, but nothing like the fish I was talking about.

On the positive side, I discovered where I'd seen the photo of the BN longfin with the odd tentacles. It is posted on Plecofanatics in their pleco ID forum, currently the last entry on pg. 18. It was posted by RicoGTI and is titled Unique Bushy Nose Pleco.

Take a look at this thing. The primary difference I see between the appearance of the tentacles on this fish and the fish in the drawing (A. eustictus?) is that on the drawing the tentacles that go up the top of the head stand upright, where in the odd BN they flop forward. Nevertheless I found the resemblance rather startling.
