A recently described phylum in the animal kingdom. Only one microscopic species, Symbion pandora, has been described. Its sessile stage is approximately 0.3 mm in length and 0.1 mm wide. Surprisingly, Cycliophora was not discovered in an exotic biotope such as a deep-sea vent or marine caves, but on the Norwegian lobster. All known occurrences are from the crustacean mouth limbs, which can be totally encrusted with thousands of the sessile stage of the microscopic animal (Fig. 1). Two other undescribed species, very similar to the type species, are found on the American lobster (Homarus americanus) and the common lobster (H. gammarus).
