Dorsal view of a juvenile transgenic zebrafish (Danio rerio) head. Veins and lymphatic vessels are visible, and the meningeal fluorescence granular perithelial cells are green. Membranes are labeled with BODIPY in magenta for background contrast, which shows the eyes, nose, lateral line neuromasts, and scales. The anterior side is on the left.
