It takes a careful eye to find this diminutive hydromedusa.  The oblong, transparent bell is at most about 12 mm tall.  Four somewhat jagged radial canals are readily visible.  The tubular stomach is completely covered by the gonad, which may be red or whitish.  Four relatively prominent tentacle bulbs are connected to 3 or 4 tentacles that may be of different lengths (depending on the species).  The bulbs and tentacles most commonly have a scarlet coloration, but may be white or yellowish.  Several species of this poorly known jelly inhabit West Coast waters from California to the Bering Sea.  It's rarely abundant anywhere within this range.
