Tentacle cnidae of the sea anemone Metridium senile (Linnaeus, 1761) (Cnidaria: Anthozoa) [PDF]
Tentacle cnidae of Metridium senile (Linnaeus, 1761) were examined by light microscopy. In addition to spirocysts, feeding-tentacles had 3 nematocyst categories grouped into medium and small size-classes, including 5 types.

Obtainment of Two Monomorphic Nematocysts from Nemopilema nomurai (Cnidaria: Scyphozoa) and Comparative Analysis of the Biological Activities of Their Contents [PDF]
Nemopilema nomurai is a species of common large toxic jellyfish in China seas, and its tentacle tissues contain various types of nematocysts. However, the correlation between the morphology and function of nematocysts still remains unclear. In this study,

Predation on scyphozoan polyps and selective hydrozoan nematocyst incorporation dynamics in an alien aeolid nudibranch [PDF]
Background Aeolid nudibranchs prey on various cnidarians and incorporate nematocysts from their prey into the cnidosac, located at the tip of their cerata for self-defense. This study examined the predator–prey interactions between two nudibranch species,

Nematocyst Types and Characteristics in the Tentacles of Gershwinia thailandensis and Morbakka sp. (Cubozoa: Carybdeida) from the Gulf of Thailand [PDF]
Nematocysts, specialized stinging cells in cnidarians, play a crucial role in both defense and prey capture, containing venomous, coiled tubes within a capsule.

Non-muscle myosin II drives critical steps of nematocyst morphogenesis [PDF]
Summary: Nematocysts are generated by secretion of proteins into a post-Golgi compartment. They consist of a capsule that elongates into a long tube, which is coiled inside the capsule matrix and expelled during its nano-second discharge deployed for ...

The proteotranscriptomic characterization of venom in the white seafan Eunicella singularis elucidates the evolution of Octocorallia arsenal [PDF]
All the members of the phylum Cnidaria are characterized by the production of venom in specialized structures, the nematocysts. Venom of jellyfish (Medusozoa) and sea anemones (Anthozoa) has been investigated since the 1970s, revealing a remarkable ...

Proteome of Hydra Nematocyst [PDF]
Stinging cells or nematocytes of jellyfish and other cnidarians represent one of the most poisonous and sophisticated cellular inventions in animal evolution. This ancient cell type is unique in containing a giant secretory vesicle derived from the Golgi apparatus.
