Dear Valda,
This is the species of Jorunna I have been calling Jorunna sp. 2. As you will see at the top of the page, this species is quite variable in colour, sometimes with large rounded spots, sometimes with scattered black specks. One distinguishing character is the median black band on the posterior tip of the foot, Fortunately in your second photo this is clearly visible.

As I discussed recently, it has close similarities to a form of Jorunna parva. Like Rostanga, species of Jorunna have a very 'bristly' back as their mantle is covered in caryophyllidia, which are small tubercles bearing a crown of pointed spicules. See Jorunna funebris for an illustration.

Best wishes,
Bill Rudman.
