Aurelia Ephyra-Stage Jellyfish

Members of the jellyfish in the class Scyphozoa undergo a complex life cycle including a larval medusa or ephyra stage. The genus Aurelia demonstrates the typical life stages for this class of invertebrates, which also include the free-swimming planula, the stalked and tentacled schyphistoma polyp, the strobila bud, and the mature medusa stages.
