WebbThe settling of planulae, strobilation of scyphistomae and release of ephyrae have been followed on ceramic settling plates which were brought to the laboratory for analysis at regular intervals. Weekly to bi-weekly hauls with Bongo nets have been used to study the abundance of ephyrae and young medusae in both surface and deep water layers.

WebbThe life cycle of Cassiopea xamachana is similar to other scyphozoans, with alternation of generations between a sessile polyp stage (scyphistomae) and dominant mobile medusa stage. The scyphistomae reproduce asexually by budding when resources are plentiful. Each newly produced bud will settle and lead to the production of another sedentary polyp.
