Volvent nematocyst, artwork. Nematocysts, or cnidocysts, 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, entrapping it. The thread is fired from a capsule within a nematocyte, 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.
