Ink Gland in Stylocheilus striatus

Dear All
Just a quick note to ask if anyone knows of a detailed drawing of Stylocheilus striatus which shows the location of the ink gland.
Thanks

Dear Angela,
As luck would have it I am preparing some anatomical diagrams at present so I can help you out. Sea Hares have two major glands in the mantle cavity. One on the roof of the mantle cavity usually secretes a red wine or purple coloured 'ink' so is often called the Purple Gland, and the second is on the floor of the cavity and secretes a thick white fluid. It is known as the Opaline Gland. In Sea Hares, such as Stylocheilus, in which the shell is lost, the 'roof' of the mantle cavity, which used to enclose the shell, is also absent, except for a small ridge on the inside of the left parapodia. The Purple Gland in Stylocheius opens on the underside of the anterior end of this ridge (purple patches in my diagram). I have marked the position of the Opaline Gland in brown.

I hope this solves your problem. I would be interested in knowing a little about your research,
Best wishes,
Bill Rudman
