Phylum Cnidaria, Class Scyphozoa & Cubozoa

Jellyfishes

Scyphozoans comprise the 'typical' jellies whose dominant adult form is a large free-swimming medusa, while the sessile polyp phase is cryptic.  As with the related hydroids, several species have been accidentally introduced to Hawaii by ships.  The Portuguese Man-o'-war is actually a hydroid but included here for convenience.
