Dear Milton and coral-listers,
Those tiny organisms are most likely ciliates of the genus
Halofolliculina; first described to cause damage in corals of the
Indo-Pacific:
- Antonius A (1999) Halofolliculina corallasia, a new coral-killer
ciliate on Indo-Pacific Reefs. Coral Reefs 18: 300
- Antonius A, Lipscomb D (2001) First Protozoan coral-killer
identified in the Indo-Pacific. Atoll Res Bull: 1-21
In 2004, they were observed for the first time in the Caribbean:
- Cróquer A, Bastidas C, Lipscomb D, Rodríguez-Martínez R,
Jordan-Dahlgren E, Guzmán HM (2006) First report of Folliculinid
ciliates affecting Caribbean scleractinian corals. Coral Reefs 25:
187- 191
- Cróquer A, Bastidas C, Lipscomb D (2006) Folliculinid Ciliates: A
New Threat to Caribbean Corals? Diseases of Aquatic Organisms 69(1):
75 - 78
Dr. Lipscomb is working on the proper identification of the Caribbean
ciliate and its relation with the Indo-Pacific one.
Hope the info is useful.
Cheers,
Carolina

Some tiny, sac-like organisms were observed in damaged tissue of a
massive
caribbean coral. They are approximately 250 microns long and have
a
tube-like opening at one end. I do not recognize these organisms
and would
appreciate help with identification or suggestions about reference
material
to consult.
Two JPEG photos of the organisms can be observed at the following
