Scyphidia (Gerda) bengalensis     (Ciliata)
Organism information awaits expert curation
Class: Oligohymenophorea

Cylindrical vase-shaped organism with a very small attachment disc or scopula. The ciliate body is highly contractile. The peristome leads into a very long gullet, entire length of which is lined internally with two rows of cilia opposing each other. The most conspicuous characteristic of this peritrichid ciliate is its cylindrical macronucleus which exhibits a great variation in its configuration, particularly in shape and length. The maximum length of the macronucleus recorded is 81.6 µm. The micronucleus with a diameter range of 1.7-3.4 µm is situated towards the oral end. There is a prominent contractile vacuole near the gullet.
