|Empty shells... : (|
The winter has passed and shells of dead snails are all around. However, those that did survive the cold, leave traces of their awakening all around their habitats. At first, I looked through the university botanical garden, but then discovered even more of them.
|A pretty epiphragm|
These tear-shaped objects are what closes the snail's shell for the winter and when the snails "wake up", they push them out with their foot and leave them around for us to find. It is called epiphragm and it is made of calcified snail slime (therefore it is also refferred to calcareous epiphragm).
|A handful of epiphragms|
Every spring, I am having great fun looking for these and this year I also engaged my pupils in looking for them during our little voluntary trip to the botanical gardens.

Aren't they wonderful? Ok, to those non-bio-nerds out there, they probably aren't, but I love them.
