Cnidocytes as Microscale Synthesis and Delivery Modules [PDF]
, 2008 Abstract : As a first step in using nematocysts isolated from Physalia in a drug-delivery patch, we needed to assess the techniques used to yield efficient discharge. A number of pre-discharge and discharge solutions were utilized to determine the best combination, chosen based on literature findings for nematocysts isolated from other species.

Mating in the box jellyfish
Journal of Morphology, 2015 ABSTRACTWithin cubozoans, a few species have developed a sexual reproduction system including mating and internal fertilization. One species, Copula sivickisi, is found in a large area of the indo pacific. They have separate sexes and when mature males and females meet they entangle their tentacles and the males transfer a sperm package, a ...

Neural pathways and innervation of cnidocytes in tentacles of sea anemones
Hydrobiologia, 2004 Our previously published studies are here reviewed detailing neuro-cnidocyte synapses, demonstrating putative neurotransmitter substances, and identifying complex neural pathways in sea anemones. Synapses were traced to their contacts on nematocytes and spirocytes by transmission electron microscopy of serial thin sections of tentacles. In five animals,

The Biological Bulletin, 2020 AbstractCnidarians, as model animals for studying conserved feeding behavior, possess the simplest nervous and digestive systems. Feeding behavior in cnidarians begins with nematocyst-mediated prey retention, proceeds to coordinated tentacle movements and mouth opening, and then proceeds to release of retained prey for ingestion.

Cnidocyte Mechanoreceptors Are Tuned to the Movements of Swimming Prey by Chemoreceptors
Science, 1989 Cnidocytes, the stinging cells of cnidarians, discharge nematocysts in response to physical contact accompanied by the stimulation of specific chemoreceptors. Cnidocytes in fishing tentacles of a sea anemone are now found to discharge nematocysts preferentially into targets vibrating at 30, 55, and 65 to 75 hertz.

The Biological Bulletin, 2014 This study investigated the localization of a voltage-gated calcium channel (VGCC) β subunit in the tentacles and cnidocytes of the Portuguese man-of-war using confocal immunocytochemistry. An antibody specific to the Ca(2+) channel β subunit of the Portuguese-man-of-war (PpCaVβ) was generated, and characterized by Western immunoblotting.

Gonadal cnidocytes in the cubozoan Tripedalia cystophora Conant, 1897 (Cnidaria: Cubozoa)
Journal of Morphology, 2019 AbstractCubozoans have a complex lifecycle in many ways similar to the scyphozoan lifecycle. The sexual reproduction within cubozoans varies between species with one clade having copulation and internal fertilization and the release of planula larvae.
