Never seen or even heard of them before. Quite a spectucalar plant indeed - we triggered a few more with a stick later but stopped when trousers and faces were splashed on.
This video shows these cucumbers in action quite well - the sound track is almost similar to when the boys first discovered them

We also came across some nice flesh eating plants amongst some harzburgite rock boulders (the real reason for the excursion) and even some wild Easter daffodils. Amazing what nature has to offer here in Cyprus - but of course we were lucky to have an expert guide to show it us all
