CHEAP snails for sale on ebay - BEWARE!
I almost ordered some of these, but found this article....
Read this before you order any cheap (as in $15-25 for 100 of them) snails!! Turns out they are not reef native, and live in colder waters. Also they can harbor all kinds of flukes that can get in your skin!!
Do You Know Who Youre Dealing With? Get to Know the Real Ilyanassa obsoleta by Mike Greenemeier - Reefkeeping.com
On Ebay like this: 265 Saltwater Nassarius Snails - Detritus Scavengers - eBay (item 220708341875 end time Jan-07-11 06:16:02 PST)
Anything listed as Nassarious Obsoleta or Ilyanassa Obsoleta
great read!!!! thanks for the heads up!!!
They could be something like a nerite or something, but flukes that we catch from snails are only in freshwater snails... (At least, I was 99% sure. Chances of a parasite that needs a mammal surviving in an ocean snail long term is slim to none.)
Thanks Bear :)
redchigh, you might want to read this then, a quote from the article:
"Ilyanassa is an intermediate host for at least nine species of trematode fluke. In most populations, over 50% of the adult snails have at least one species of this parasite, and in some populations the rate of infection is as high as 94% (Curtis and Hubbard, 1990; Curtis, 1997)! While none of these flukes actually targets humans as hosts, they do sometimes mistakenly burrow into human skin and cause what is known as "swimmers' itch," or more properly, cercarial dermatitis (Sindermann, 1960). This condition creates an extremely itchy rash similar to poison ivy that can last for up to a week. Affected snails will continue to release the infective stage of these flukes into a tank for up to a decade (assuming the snails live that long), and any exposure to the tank's water puts the aquarist at risk of infection (Curtis et al., 2000). Interestingly enough, the flukes that infect Ilyanassa harm them not only by stealing nutrition and castrating the animals, they can also actually control the snails' behavior. Infected snails make more frequent trips to, and go higher into, the intertidal zone where they are more likely to encounter birds and crustaceans, which are the flukes' primary hosts (Curtis, 1993). Coincidentally, that's also where they are more likely to encounter livestock collectors. As a result of this behavioral modification, it's highly likely that collectors of these snails have an unintentional bias toward infected specimens."
I just read a book on parasites. I think I had liver flukes on the brain, saw fluke, and read it as liver fluke.
Liver flukes do the same thing, making the snail go up to higher surfaces, but they'll also crawl into the snail's eyestalk and make it look like a catipillar. :P
