What Happens to Fats Eaten by Fish? (IMAGE) Carnegie Institution for Science Caption This is a live image of the liver of a translucent, larval zebrafish. It was taken using confocal microscopy, which allows for clear images of the internal organs of a whole live animal. Quinlivan fed a fluorescently tagged fatty acid to a larval zebrafish and then photographed its liver at 400x magnification. The round dots of varying sizes are lipid droplets, which contain a kind of fat called triglyceride. These triglycerides were constructed using the fluorescent fat consumed by the larval zebrafish. Fluorescence also shows up in the gallbladder (GB) and developing kidney (K).
