Nematocyst Types and Characteristics in the Tentacles of Gershwinia thailandensis and Morbakka sp. (Cubozoa: Carybdeida) from the Gulf of Thailand

Biology
Nematocysts, specialized stinging cells in cnidarians, play a crucial role in both defense and prey capture, containing venomous, coiled tubes within a capsule.

Haemolytic activity and characterization of nematocyst venom from Pelagia noctiluca (Cnidaria: Scyphozoa) [PDF]

, 2013
We investigated the haemolytic capacity of the crude venom extracted from isolated nematocysts of Pelagia noctiluca (Cnidaria: Scyphozoa), and evidenced the proteic fractions responsible for this activity.

New Class of Crosslinker-Free Nanofiber Biomaterials from Hydra Nematocyst Proteins [PDF]

Scientific Reports, 2019
Nematocysts, the stinging organelles of cnidarians, have remarkable mechanical properties. Hydra nematocyst capsules undergo volume changes of 50% during their explosive exocytosis and withstand osmotic pressures of beyond 100 bar.

A fast recoiling silk-like elastomer facilitates nanosecond nematocyst discharge [PDF]

BMC Biology, 2015
BackgroundThe discharge of the Cnidarian stinging organelle, the nematocyst, is one of the fastest processes in biology and involves volume changes of the highly pressurised (150 bar) capsule of up to 50%.

Quantitative Insights into the Contribution of Nematocysts to the Adaptive Success of Cnidarians Based on Proteomic Analysis

Biology, 2022
Nematocysts are secretory organelles in cnidarians that play important roles in predation, defense, locomotion, and host invasion. However, the extent to which nematocysts contribute to adaptation and the mechanisms underlying nematocyst evolution are ...

Morphological and molecular analysis of the Nematostella vectensis cnidom. [PDF]

PLoS ONE, 2011
The starlet sea anemone Nematostella vectensis is an emerging model organism for developmental and evolutionary biology. Due to the availability of genome data and its amenability to genetic manipulation Nematostella serves as a source for comparative ...

The architecture and operating mechanism of a cnidarian stinging organelle

Nature Communications, 2022
The venomous stinging cells of jellyfish, anemones, and corals contain an organelle, the nematocyst, which explosively discharges a venom-laden thread.

Neuro- and Cardiotoxins from Sea Anemones: Structure, Function and Potential of Application in Research and Medical Practice

Вестник войск РХБ защиты, 2023
Sea anemones are well-spread everywhere in the World Ocean and represent the most ancient active poisonous organisms. Their main instrument of attack on other animals are the nematocysts – stinging organelles with the curtailed hollow thread with ...
