Comments : This specimen was a bit big for my 3T lens, but I got the best shot I could. The Plainfin Midshipman is a member of the Toadfish family. It's claim to fame is it's bio-luminescent spots along it's underside. This fish often buries itself in the mud during the day, then hovers motionless above the bottom at night, presumably attracting prey with it's bio-luminescent spots. I often see small Midshipman (about 2 inches long) in the shallows on night dive at Three Tree Point.
