SUCTORIA
(insert pic, preferably a slide, but a lab drawing will do, need help finding one)
Adult Suctoria are typically predatory and unciliated. They fall into the Ciliate group because they produce one or several ciliated ‘swarmers’ by exogenous, internal, or evaginative budding.
Swarmers have a short existence. They lose cilia, metamorphose into adults and anchor themselves to the substratum. The adult looks similar to a tulip with tentacles.
(insert slide of suctoria and label)
Structures to note include

  1. bell shaped cell body

  2. tentacles that extend all the way around the bell

  3. macronucleus, large pink body shaped like a “C”

  4. stalk, may be very faint

  5. feet, to anchor the adult to the substratum


*Note: Obelia stalk in the substratum, not part of the Suctoria cell
