As anthropogenic stressors increasingly impact our oceans, jellyfish may become more prevalent within marine communities, which has a number of ecological and socio-economic implications. This draws our attention to how future climate scenarios will influence jellyfish physiology, and therefore the likelihood of population sizes rising in upcoming years. However, experimental data demonstrating how environmental stressors influence jellyfish physiology is limited. Data considering the potential influence of global warming on growth, behaviour, and morphology of the scyphozoan jellyfish Cassiopea sp. will be presented. Following strobilation, individual development and a suite of morphometrics were tracked over a three-month period. This data is used to assess plasticity and resilience to environmental parameters in relation to climate change. These parameters are also evaluated in Cassiopea sp. reared in darkness to assess of how temperature effects vulnerability to an additional stressor. Finally, environmental drivers of jellyfish morphology that may be considered for taxonomic research are highlighted.
