In response to Annie Lindgren's recent questions on nudibranch nematocysts:
There are few published studies on the turnover rate of nudibranch nematocysts. See the following review paper:
• Greenwood PG. 1988. Nudibranch nematocysts. [In] The Biology of Nematocysts. Academic Press. 445-462.

Greenwood also cites:
• Day, R.M. & Harris, L.G. (1978) Selection and turnover of coelenterate nematocysts in some aeolid nudibranchs. The Veliger, 21(1): 104-109.
• Conklin, E.J. & Mariscal, R.N. (1977) Feeding behavior, ceras structure, and nematocyst storage in the aeolid nudibranch, Spurilla neapolitana (Mollusca). Bull. Mar. Sci., 27: 658-667.

I also suggest reading some of the literature on turnover of chloroplasts in sacoglossans. Although by no means a homologous system, I think it gives an interesting perspective on the storage and maintenance of organelles originating from prey organisms.Best of luck with your project Annie!
