This fella is a 'Leaf Scorpionfish'. I'll spare you the latin name. It is relatively rare and seldom seen let alone photographed to any extent. Its MO is rather unusual as its disquise is that of a leaf. Its body sways and undulates like a submerged leaf underwater. Note the transluscence of its body near the tail where you can see the backbone and slender ribs. 120' Loloata Island, PNG. Fish Portrait Series.
