Littorina fabalis

Littorina fabalis

Observation - Littorina fabalis - UK and Ireland. Description: Littorina fabalis seems distinctly triangular or at least angular. Flatter than Littorina obtusata. I don't think this shell, here, can be confused with L.obtusata, the common Flat Periwinkle. It also seems a very fine shell here. This post is now link

ADDED 22 March 2015What a mixed bag of possible errors here - shells shown may not be of the subject given and the only sound observation is given by JoC in Comments here http://www.ispotnature.org/node/328587#comment-111361. Ordinarily such misleading posts should be removed from resource but MUCH value can be found in discussion.
