Uncharismatic Fact of the Day
Who doesn't love bubbles? Plerogyra sinuosa is more commonly known as the bubble coral due to its uniquely shaped appendages called polyps. During the day they inflate, resembling large bubbles or fish eggs, which allows the dinoflagellates living inside it to photosynthesize. At night the polyps deflate and collect plankton from the surrounding water.
