[Cnidaria] nematocyst envenomation

[ottuso at comcast.net]

Hi Angel. Thank you for your response. 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.
