REFER TO NEXT PIC IN THE STREAM: This is the first time I have come accross this type of creature. Not sure what it is? A snail / slug ? It is covered in this wonderful soft hair mass , the bigger they are the more wonderful the hair growth (kind of like Neptune!) They are soft to the touch with a soft under belly which is similar to a slug. The next picture in the stream shows what they look like when left out of the water - beautiful colours - I am not sure if they leave behind a shell or not........ Hassan, Perhaps you can fill us in???? ;-)
