Snails of Cuba! In the end, we found 5 species, including the most endangered and arguably also most beautiful, Polymita sulphurosa. Unfortunately, we also encountered illegal sale of the shells on mountain pass.

Why? Project is on the evolution and conservation of these snails, led by Dr Bernardo Reyes in Cuba and working with colleagues from London zoo, Netherlands, Belgium, and Germany.

#Snails are primarily marine #mollusks. According to current hypotheses, the #sistergroup might be #Cephalopoda plus #Scaphopoda (Link below) . One #Apomorphy, i.e. evolutionary new acquisitions of the stemspecies, is the #asymmetrical #shell that is wound in one direction, which is due to a #torsion of the #mantle and visceral sac.
The species in my #photos is #Cornu #aspersum from Italy. #biodiversity,

It has everything known about the magician treesnail 🧙🐌 - a species long under the radar.
A highlight is the use of CT scans to observe internal anatomy.
