Volvent nematocyst Artwork of a nematocyst,or cnidocyst,before (left) and after (right) discharge. Nematocysts are usually venomous threads that are found in Cnidaria,which includes jellyfish,sea anemones and corals. A volvent nematocyst doesn't contain any venom. Instead it wraps around its prey (green),entrapping it. The thread (red) is fired from a capsule (black) within a nematocyte (khaki),or cnidocyte,a specialised organelle. Firing is initiated when a hair-like trigger,the cnidocil (at top right of structure) is activated by passing prey | |
