Figure 1

Photo of Tetraplatia volitans, roughly 8 mm in length (a), diagrammatic sketch of T. volitans (b), and sketches of two cnidarians that have been hypothesized to be close relatives of Tetraplatia, (c) a coronate (Scyphozoa) and (d) a narcomedusan (Hydrozoa). T. volitans (b) drawn by Keiko Hiratsuka Moore; Ephyra of Linuche unguiculata (c) after Mayer (1910); Aegina citrea (d) after Mayer (1910). In all cases, views are perpendicular to the oral–aboral axis and the oral end is directed down.
