Hello again! Thank you for the responses that I have already received
about Trichotropis specimens (and other snails in the Tichotropidae family).
Based on a suggestion from one of the
people who replied to my plea for specimens, I wanted to clarify what I
am interested in. I am not only interested in the specimens (which would
be nice), but exact locality data and information on what the snails
were on--not just the habitat they were in, but whether they were on
worms, bivaves, etc. Trichotropis cancellata (the species I am mostly
working on) is a facultative kleptoparasite (can suspension feed on its
own and can also steal food from tube-dwelling polychaete worms) so I am
trying to figure out if other species in the genus are also potential
parasites. Thus, knowing what,if anything, they are sitting on is very
important. Unfortunately many museum specimens that I have seen have
very inexact site localities (naming an entire large island in southeast
Alaska, for example). So I am trying to locate sites that might be good
places for me to go to collect the snails myself and make observations in
situ using SCUBA, as well as seeking specimens (preserved or live) on which
to do morphological studies of the gills and pseudoproboscis.
Thank you again for any help/suggestions you have. I can be contacted
directly at [log in to unmask] (which might be kinder on other listserve
readers who are not interested in Trichotropis! :-> )
Thanks!
Erika Iyengar
