Abstract

Several morphotypes of the relatively large bacterium, Epulopiscium sp. were collected from the intestines of three species of surgeonfish (genus: Acanthurus) from shallow waters around the island of St Thomas, in the eastern Caribbean Ocean. This was the first comprehensive study of any of these bacteria from the Atlantic Ocean. They were chemically fixed at the University on St Thomas Island, Virgin Islands and sent to the first author (J.N.G.). Each sample was examined under phase-contrast microscopy with a light microscope. Most cells contained two daughter cells that were very phase-bright; hence, were likely true endospores. They varied from very small, at the ends of the cell, to one-third the length of the cell length to overlapping at the centre. A few contained only one daughter cell or endospore. Based on their si-Aes, shape, and number of daughter cells, they best fit two of the morphotypes described previously.
