Determining the population structures of cubozoan jellyfishes with biophysical modelling

, 2020
Jodie Schlaefer studied box jellyfish. She found that self-contained stocks were separated by only tens of kilometers, challenging the paradigm that jellyfish populations are well mixed over large distances. The occurrence of box jellyfish is unpredictable because their abundance is influenced by conditions at the small spatial scale of stocks.

Towards understanding the phylogenetic history of Hydrozoa: Hypothesis testing with 18S gene sequence data

Scientia Marina, 2000
Although systematic treatments of Hydrozoa have been notoriously difficult, a great deal of useful information on morphologies and life histories has steadily accumulated. From the assimilation of this information, numerous hypotheses of the phylogenetic

Comparative effect of cnidarian venoms on the action potential firing of superior cervical ganglion neurons

Journal of Biological Research
Cnidarians are considered the most ancient venomous phylum on Earth. Their venom is a complex mixture of bioactive compounds that produce a myriad of signs and symptoms in humans.

Eye Development in the Cubozoan Jellyfish Carybdea Marsupialis [PDF]

, 2011
Cnidarians are the most primitive invertebrates alive today to possess eyes. The complex eyes of the cubozoan jellyfish Carybdea marsupialis exhibit many similarities to the camera-type eyes of higher metazoans including the presence of a cornea, lens ...

First aid treatment of the sting from the hydroid Lytocarpus philippinus: the structure of, and in vitro discharge experiments with its nematocysts

, 1993
Brush contact with colonies of the stinging hydroid Lytocarpus philippinus by divers and snorkellers causes itchy painful weals for which no first aid measures have yet been devised. Laboratory experiments were performed using common household substances

The Cubozoan Nervous System:From Neuropeptides to Learning Formation in the Box Jellyfish Tripedalia cystophora

, 2021
Cnidarians have long been recognized as occupying a unique position in the nervous system evolution, and consequently, have attracted considerable attention from neurobiologist throughout the years. Currently researchers have focused on the box jellyfish,

Evolution of box jellyfish (Cnidaria: Cubozoa), a group of highly toxic invertebrates

, 2010
Cubozoa (Cnidaria: Medusozoa) represents a small clade of approximately 50 described species, some of which cause serious human envenomations. Our understanding of the evolutionary history of Cubozoa has been limited by the lack of a sound phylogenetic ...
