You can easily recognise the Geometric moray by the dashed lines patterning its face and body. These are pores of its lateral line system. This detects changes in pressure so the moray can detect movement and vibration in the surrounding water. Moving with
snake-like motions, they are extremely quick. When at rest
you may see them rhythmically opening and closing their
mouths. They do this to maintain a respiratory current
past the gills…
