A visual opsin from jellyfish enables precise temporal control of G protein signalling
Nature Communications, 2023 Phototransduction is mediated by distinct types of G protein cascades in different animal taxa: bilateral invertebrates typically utilise the Gαq pathway whereas vertebrates typically utilise the Gαt(i/o) pathway. By contrast, photoreceptors in jellyfish

Comparative Aspects of Structure and Function of Cnidarian Neuropeptides
Frontiers in Endocrinology, 2020 Cnidarians are early-branching animals in the eukaryotic tree of life. The phylum Cnidaria are divided into five classes: Scyphozoa (true jellyfish), Cubozoa (box jellyfish), Hydrozoa (species, Hydra and Hydractinia), Anthozoa (sea anemone, corals, and ...

Velarium control and visual steering in box jellyfish. [PDF]
J Comp Physiol A Neuroethol Sens Neural Behav Physiol, 2013 Directional swimming in the box jellyfish Tripedalia cystophora (cubozoa, cnidaria) is controlled by the shape of the velarium, which is a thin muscular sheet that forms the opening of the bell. It was unclear how different patterns of visual stimulation control directional swimming and that is the focus of this study.

Cell proliferation in cubozoan jellyfish Tripedalia cystophora and Alatina moseri. [PDF]
PLoS ONE, 2014 Cubozoans (box jellyfish) undergo remarkable body reorganization throughout their life cycle when, first, they metamorphose from swimming larvae to sessile polyps, and second, through the metamorphosis from sessile polyps to free swimming medusae. In the
