The maximum bell height observed in "M. virulenta" can range up to 250 mm and the bell width can range up to 200 mm. The bell of "M. virulenta" is rectangle-shaped and covered with nematocyst warts. "Morbakka virulenta" can be distinguished from other species in the family by its heavily branched velarial canals as well as two rows of perradial warts with additional scattered warts.
