Just put your mouse over an image and move left/right to control the slider – no need to click.
Zebrafish expressing cmlc:GFP (heart) and gata1:dsRed (blood cells)
Royal Blue excitation shows the strong green heart fluorescence, with weaker expression from the blood cells. The yellow is autofluorescence from the yolk.
Green excitation brings out the red fluorescence in the blood cells.

Coral recruits on settlement tiles, under the microscope
Fluorescence is a powerful tool in the study of juvenile corals and coral recruitment. Specimens that are hard to see in white light jump out in fluorescence.
