10:45 A PRELIMINARY REPORT ON IDENTIFYING CNIDARIANS
USING MOLECULAR TECHNIQUES
Kelp bass diet consisted of ten prey groups: eelgrass fragments, cnidarians
, mollusks, polychaetes, mysids, decapods, gammarids, caprellids, isopods, and fishes.
Abstract: A suite of fossils collected from the Warsaw Formation (Mississippian) of Missouri includes brachiopods, bryozoans, cnidarians
, poriferans, echinoderms, and chondrichthyan teeth.
Where the seabed consists of rocks, mobile fishing gear removes large epifaunal invertebrates (such as sponges, cnidarians
, and bryozoans) and moves boulders along the bottom.
The series will devote hour-long programs to eight of the major body plans--sponges, cnidarians
(jellyfish and kin), flatworms, mollusks, annelids (earthworms) arthropods (insects, spiders, lobsters), echinoderms (starfish, sea urchins) and chordates (fish, birds, humans).
While jellyfish and other cnidarians
have nerve cells that form a loose network in their bodies, comb jellies have a more sophisticated nervous system with a rudimentary brain and cellular connections called synapses that are also found in flies, humans and most other animals.
Plankton samples were comprised of primarily crustaceans (copepods, amphipods, euphausiids, and decapod (brachyuran, pagurid, caridean) larvae) and chaetognaths with some polychaetes, gastropods, cnidarians
, echinoderm larvae, and fish larvae and eggs; no red, blue, or golden king crab larvae were present.
The lower Pridoli (Varnytsya Fm) has yielded brachiopods of the Atrypoidea gigantus, trilobites of the Acaste podolica and Proetus scalicus and cnidarians
of the Stelopora rara communities, all belonging to BA 2.
This family also includes well-known creatures such as jellyfish and corals, which, like other cnidarians
, have the simple design of a mouth surrounded by tentacles.
