what are zooxanthellae
Zooxanthellae are single-celled plants that live in the tissues of animals. They are dinoflagellates, a group of microscopic plants which are usually found swimming and floating in the sea.Organisms which live like this are called plankton, and those that are plants are called phytoplankton.ere are some photos of zooxanthellae living in nudibranchs. To see all the parts of the zooxanthellae, we have to cut it into very thin slices, and then photograph each slice. Because of this, not all these photos show all the different parts of the cell.
