The Effect of Stretching on the Rate of Conduction in the Neuro-Muscular Network in Cassiopea [PDF]
Proceedings of the National Academy of Sciences, 1917 It was observed by Carlson (Amer. J. Physiol., 27, 1911, 323) that stretching the nerve of the slug has no effect on the rate of the nerve impulse. This does not support Bethe's hypothesis that the impulse passes over solid neuro-fibrillae which are zig-zagged in the relaxed nerve and straightened out in the stretched nerve.

, 2022 Scyphozoans of the genus Cassiopea are notable for their unusual benthic habitat of lying upside-down with their exumbrella resting on the substrate and oral arms facing upwards, resulting in their common name “upside-down jellyfish”. Cassiopea are model

Cassiopea Lake Alexandria, Northern Territory, Australia
, 2011 Quantitative measures of densities of the 'upside-down' jellyfish, Cassiopea sp., were made at Lake Alexandria, an artificial saline lake in Darwin, Northern Territory, Australia on 29-10-2003.

RHO CASSIOPEAE - GIANT OR SUPERGIANT ?
Odessa Astronomical Publications, 2017 Variable polarization of ρ Cassiopeae is found, with an amplitude of about 0.2 in the V band and up to 1 in R. It is drew attention on a conflict of luminosity from a spectral analysis (about -8 magnitude) and from a trigonometrical parallax (an average from four measurings corresponds to +0.5 magnitude).

Cassiopea xamachana Cellular Dissociation v1
This protocol is to optimized to dissociate and fix Cassiopea xamachana cells for cell sorting and scRNA-seq. The dissociation by itself results in 53-55% of viable cells. Cells cannot be sorted without fixative, unless your machine can sort a seawater solution. Any other solution will lyse cells.

Variation in host-symbiont compatability among Cassiopea-algal symbioses
, 2003 textSurprisingly few empirical studies have addressed the evolutionary ecology of mutualisms. In particular, there are few data available that address the following crucial questions: 1) what factors align the interests of symbiotic partners?
