A brown colored Leaf Scorpionfish (Taenianotus triacanthus) hidden deep within an artificial reef structure on the house reef at the SMART dive resort on Mabul Island in Sabah, Malaysia.
These thin bodied fish wave back in forth in the current and thus move like a leaf. Like all other scorpionfish, these are ambush predators and they use their appearance to literally hide in plain site waiting for prey to swim or move close by. They are extremely difficult to see, even when in plain sight.
