Re: Breeding Journal, Species: Nassarius cf. pauperi

These type of Nassarius are pretty widespread in Colorado. We need to get Joe to bring you guys some starters. These little guys are great. Excellent detrivores and they remain very small (less than 1/2").

hrmm remind me to illustrate the way to tell whether or not a snail has a pelagic larval period or not by looking at it's apical whorl. Nifty Trick I learned from the good Dr. Shimek (that guys full of wisdom!!) As far as getting the snails out Gale, I shipped some out to Chad a few months ago, he's controlling distribution currently. I've got to get more out to others including Carmie Jo and welll... the list is long. I gotta get shipping, it's on me at this point!

Pass down the knowledge Joe! That's cool, I've never heard that about the apical whorl before. I guess I don't hang around the places that the good doctor posts. Try and get him to check in over here once in a while hehe.

Lol gale, to be brutally honest I cant even take credit for the questioning!!! Brian Plankis at one point pinned down Shimek regarding the Nassarius trying to get a tentative ID and he gave a pretty good description of how to examine the apical whorl (first whorl) of a snail shell to determine whehter or not it was benthic or pelagic. Smooth and rounded = benthic like our little guys vs. rough and pitted = pelagic like many others. makes perfect sense as the apical whorl is the first part of the shell to form, if spent time in the column one would expect rough and pitted formation wherease within the confines of the protective egg capsule the apical whorl can form mostly undisturbed. I'll try and dig that thread up (no doubt andy may beat me to it). Truth be told that little gem I blame for me getting into the hobby so much. the idea that you can tell so much about a species simply by observing the first nub on a shell blew my mind... and I've been spinning my wheels trying to get a verified ID on this species since. In fact, it was Shimek that recommended the cf. denotation to point out that we are certain the Genus is Nassarius but we are uncertain that the species is pauperi. and thus my work continues, this little snail has made it into every little aspect of my life.. I have them everywhere, I take notes every day. This stupid snail is the reason I got into the hobby with such pinache and the reason why I feel inadequate as a researcher..... stupid snail

I think it's the distance between the first few whorls. If it spends much time in the plankton then the whorl gets elongated because the snail can't grow as much (or it would fall out of the plankton). That's what I understood Ron to have said.

hrmm good point Andy, I'll go back and re-read both situations make sense! I should probably read into that one a little more (and maybe get some clarification during MACNA) and get that info posted up for everyone else.
