Background

The Cochlicopa lubricella (Poro 1938) has long been thought to be a variety of the Cochlicopa lubrica (Muller 1774). (Outerio, et al. 1990)  However in 1954 Quick redefined it as its own species and later in 1960 Hudec found further differences between the two species. (Outerio, et al. 1990)   An overall observation between the two is the mean of the height-diameter ratio for the Cochlicopa lubricella (Poro 1938) population is usually greater than that of the Cochlicopa lubrica (Muller 1774)  However this is not always the case. (Outerio, et al. 1990)  Other research has been done and some authors are very doubtful Cochlicopa lubricella and Cochlicopa lubrica (Muller 1774) are even different species.  (Outerio, et al. 1990)  The Cochilcopa lubricella (Poro 1938) is separated into a couple different types and in one study according to the genetic data Type 1 Cochlicopa lubricella (Poro 1938)  and Cochlicopa lubrica (Muller 1774)  should be considered the same thing. (Armbruster 1997)   The original system for identifying between the Cochlicopa lubricella (Poro 1938)  and Cochlicopa lubrica (Muller 1774))  was by their shell but now we know that looking at their genes is a lot more reliable, and shows that these to species clearly overlap.  (Armbruster 1997)  Recent genetics research gives evidence that there is an obvious difference between most Cochlicopa lubrica (Muller 1774)  and Cochlicopa lubricella (Poro 1938)  and they should not all be considered the same group of snails.  (Armbruster 1995)  Now that we no know the background lets take a look at their life like where they live, how they reproduce and other fun facts.
