Interspecific mucus enhanced
nematocyst discharge by 44% and spirocyst discharge by 90%, as compared to baseline discharge obtained in seawater alone.
Several studies on [PLA.sub.2] from venom sources such as rattlesnake, Crotalus durissus cascavella, venom [15] and sea anemone, Aiptasia pallid,
nematocyst venom [29] also showed strict [Ca.sup.2+] requirement [30].
Purification and partial characterization of the phospholipase A2 and co-lytic factor from sea anemone (Aiptasia pallida)
nematocyst venom.

Severity of Irukandji syndrome and
nematocyst identification from skin scrapings.
Tentacles have intermittent ridges of
nematocyst batteries within the epidermis.
These analyzed specimens of Gonionemus have: around a 10 mm width, four radial channels, a manubrium shorter than the umbrella cavity, a mouth with four lips slightly crenulated, four folded gonads along radial channels leaving the distal part free, between 40 and 44 hollow tentacles, each tentacle has ring-like
nematocyst clusters and adhesive pads near the distal end, and one or two statocysts between successive tentacles enclosed in mesoglea near ring canal with a single endodermal club.
The correlation between
nematocyst types and diets in pelagic hydrozoa.
A simplified identification key, redescriptions, illustrations and data on
nematocyst compliment are provided for each species.
We thus estimated the relative tentacle length by counting the number of stenoteles (a type of
nematocyst) throughout a tentacle.
A final visit to the Jawbone on 4 August 2012, in poor weather, yielded a 12 mm juvenile specimen, which was used for live
nematocyst observations.
