SUCTORIA
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.
Structures to note include
A bell shaped cell body
B tentacles that extend all the way around the bell
C macronucleus, large pink body shaped like a "C"
D stalk, may be very faint
E feet, to anchor the adult to the substratum
*Note: Obelia stalk in the substratum, not part of the Suctoria cell
