Morphology and Molecular Phylogeny of Endosymbiotic Ciliates (Peritrichia, Mobilida) of Marine Invertebrates with Descriptions of Two Novel Species Urceolaria clepsydra n. sp. and Urceolaria bratalia n. sp.

Journal of Eukaryotic Microbiology, Volume 72, Issue 2, March/April 2025.
ABSTRACT Mobilid ciliates are a morphologically distinct group of protists that form a wide range of symbiotic relationships with aquatic animals and includes three subgroups: Trichodinidae, Urceolariidae, and Polycyclidae. Trichodinids are best known for infecting fishes, whereas urceolariids infect diverse marine invertebrates.
