Dear Patrick,
please see my message below and a picture of nematocysts in the attachment. When I sent you that massage my e-mail box wrote that your address failed... no idea ))
I hope Cnidaria list will help, please let me know when you receive this letter.
cheers,
Sonya

For the article I am looking for an image of nematocysts that may be incorporated into nudibranchs for self defense and if possible, a clinical photo of the specific types on nudibranchs that use this defense. I would also like images of nematocysts in the non fired and firing mechanisms.--The latter images would be shown at next years American Acad. of Dermatology annual mtg. as I am the director of a focus session re marine dermatology. Thanks, Patrick.
