Discoidal structures occur on at least three horizons (two of which are well exposed at the McKay Highway outcrop), and all share similar morphologic features, including features that are common to cnidarian
10:45 A PRELIMINARY REPORT ON IDENTIFYING CNIDARIANS USING MOLECULAR TECHNIQUES
Craspedacusta sowerbii Lankester (Cnidaria: Hydrozoa) is the only species of freshwater cnidarian
in North America exhibiting a medusa stage in it's life cycle.
In May 2010, however, Simpson and his colleagues reported in PLoS ONE the first evidence that coral larvae (and larvae of any cnidarian

In the more traditional sense, Lucas says, the term "jellyfish" applies just to the watery species in the stinging cnidarians
, and she sometimes narrows even further to a subgroup called scyphozoans.
Jellyfish are intriguing and dazzling; ocean-dwelling cnidarians
