What a mug!  This toadfish was not happy to have a dive light shining into his nursery.  He was busy guarding his young in a dark and quiet cave under a coral head, one of many potential homes along a sandy slope off the island of Mutus (Raja Ampat, Indonesia, Nov 2010).  His young were even less excited to be woken up.  Look closely and you'll see they're all making tracks to the back of the cave, most of them leaving us with the ever-popular fish butt shot (cropped close up below).  

Think of this scene if you hear people talking about temperate toadfish waking them up in the night.
