The importance of molecular characters when morphological variability hinders diagnosability: systematics of the moon jellyfish genus Aurelia (Cnidaria: Scyphozoa)
Cryptic species have been detected across Metazoa, and while no apparent morphological features distinguish them, it should not impede taxonomists from formal descriptions.We 2004 hyundai santa fe catalytic converter accepted this challenge for the jellyfish genus Aurelia, which has a long and confusing taxonomic history.We demonstrate that morphol
