Each data point represents a mean number of nematocysts
counted per field of view for two replicate experiments, each consisting of eight test probes.
A guideline to nematocysts
nomenclature and classification, and some notes on the systematic value of nematocysts
The toxin isolated from nematocysts
of Chrysaora is known to depolarise nerve and muscle membranes and to increase the frequency of miniature end-plate potentials.
The total range in length and width was 540.0-654.5 [micro]m and 101.4-152.7 [micro]m respectively, with nematocysts
spread all over, some protruding from the surface.
Purification and partial characterization of the phospholipase A2 and co-lytic factor from sea anemone (Aiptasia pallida) nematocyst

were isolated from the dissected tentacles as described in a Bloom method with slight modification .
These specialized cells have special parts called nematocysts
that contain venom.
lactea cnidome (the set of nematocysts
of a species) is well-known (Morandini & Marques, 2010) although there are no toxicological studies for this species.
Jellyfish sting using nematocysts
, which are located in special cells called cnidocytes on the tentacles.
Several studies suggest that vinegar can counter the effects of the venomous nematocysts
that a jellyfish releases during an attack.
These soft-bodied sea anemones provide a unique habitat for anemonefishes, which are protected from piscivorous fishes by the anemones' nematocysts
. Furthermore, host anemones beneft from the presence of anemonefishes as they are aggressive against specialized anemone predators such as chaetodontids, and attack them more than they do non-predatory fishes in close vicinity (15).
