Creatures of the night -- part 1

During the day we encounter lots of fish that are hanging out in dark recesses of the reef.  Many of these fish are red and have really big eyes.  These fish leave their daytime hiding places when it is dark.  At night, they move into the water column where we see their eyes, which reflect light, for quite a distance.

The glasseye snapper and various squirrelfish are nocturnal hunters. These fish grow to about 12 inches, but the ones in the photos below were 8 to 10 inches.  The photos were taken at depths of 35 to 50 feet.
