Semaeostomeae
Semaeostomeae (literally "flag mouth") is an order of large jellyfish characterized by four long, frilly oral arms flanking their quadrate mouths. The umbrella is domed with scalloped margins, and the gastrovascular system consists of four unbranched pouches radiating outwards from the central stomach; there is no ring canal.[1]
