Amphioxus (3 of 3) (image) University of California - San Diego Share Print E-Mail Caption Under white light (top), amphioxus appears whitish/translucent. Under epifluorescence (bottom), amphioxus exhibits strong green fluorescence in the head part (arrow), while the rest of the body is either slightly fluorescent or not at all. Different parts of amphioxus seem to express different GFPs, with distinct fluorescence capacity and/or antioxidant capacity.
