NEMATOCYST MAINTENANCE AND ORIENTATION IN AEOLID NUDIBRANCHS

Unknown Date (has links)
Many aeolid nudibranchs that feed on cnidarians incorporate their prey's stinging capsules, called nematocysts, into their own cells. Unfired nematocysts are maintained within the cnidophage cells of cnidosacs at the tip of each ceras. I investigated several aspects of the nematocyst incorporation process in this study, including nematocyst maintenance and orientation in several species of nudibranchs. / At least one species of nudibranch, Spurilla neapolitana, stores late-stage immature nematocysts that subsequently complete development in the cnidosacs. I found that isolated nematocysts used molecular energy in the form of ATP and do not complete development without it. Because isolated nematocysts require ATP for their maintenance, it is probable that nematocysts in nudibranch cnidophages also require ATP or a similar energy source. / Nematocysts are oriented within the cnidophages by the cytoskeleton. Microfilaments and microtubules draw the nematocysts into the cnidophage and hold them in the cell with their apical or firing ends pointed toward the cnidosac lumen. Thus, the nematocysts are oriented so they fire away from the nudibranch when released. / A comparative ultrastructural study of five nudibranch species revealed differing cnidosac structures among species and particularly between anthozoan feeders and hydrozoan feeders. These differences suggest that both the mechanisms of nematocyst maintenance and the ways that nematocysts are released differ among nudibranchs depending on their prey. / The results of this study indicate that nematocyst incorporation by nudibranchs is more complex than previously supposed. Acquired nematocysts are not simply held in cells until their release, but are incorporated into cnidophage cells in a complex process, oriented by the cytoskeleton, and actively maintained within the nudibranch. / Source: Dissertation Abstracts International, Volume: 48-07, Section: B, page: 1911. / Thesis (Ph.D.)--The Florida State University, 1987.
