Early observations of the cubomedusae Carybdea marsupialis suggest that muscle cells are organized in longitudinal tubes contained within the mesoglea of the tentacles (Claus, 1878).
Herein we present the current status of knowledge of the ecology of the scypho- and cubomedusae fauna from the southwestern Atlantic and Subantarctic region, encompassing Uruguayan and Argentine shelves and their adjacent oceanic waters between 32-60[degrees]S, 34-70[degrees]W (Fig.
Further, we test the functionality of the regenerated rhopalium by using electrophysiology, and we seek additional evidence for giant neurons functioning as pacemaker cells in cubomedusae.

Here I provide an electrophysiological examination of conduction systems that underlie three types of acute responses in cubomedusae, to help understand the subsystem components within the cubomedusan nervous system.
In view of the abundance of sensory cells on the rhopalium itself, it has been suggested that body position relative to gravity is detected on a larger scale, with the statolith acting as a "weight" only, as has been proposed for cubomedusae (Garm et al., 2011).
In cubomedusae, the FMRFamidergic system in the subumbrella is almost exclusively contained within the rhopalia and nerve ring, without the diffuse nerve net organization seen in scyphomedusae (Satterlie, 2002, 2011).

Cubomedusae have four rhopalia, one on each side of the bell (Fig.
The research described here was prompted by a request from the Queensland tourism industry to find whether lights of different colors might elicit different behavioral responses from cubomedusae; specifically, could a light be found that does not attract irukandjis and box jellies?
Cubomedusae are remarkable among cnidarians for their complex, lensed eyes and the rapidity and accuracy of their swimming adjustments in response to visual stimuli.
