Abstract In sessile animals, body surface-associated water currents are essential for integrating feeding, cleaning, and boosting metabolic exchange across colonies or communities of solitary individuals. The evolutionary origins of surface currents and their distribution among cnidarians remain poorly understood. Here, we investigated directional surface currents by tracking moving fluorescent beads on live specimens.

Abstract The life cycle of most medusozoan cnidarians is marked by the metagenesis from the asexually reproducing sessile polyp and the sexually reproducing motile medusa. At present it is unknown to what extent this drastic morphological transformation is accompanied by changes in the cell type composition. Here, we provide a single cell transcriptome atlas of the cosmopolitan scyphozoan Aurelia coerulea focussing on changes in cell-type composition during the transition from polyp to medusa.
