CRITTER: Meet nohu the Leaf Scorpionfish

  • Terry Lilley / Contributed

    The leaf scorpionfish can be brown, black, white, yellow, green or pink.

This 4-inch slow moving reef fish is almost impossible to see but can cause a powerful venomous sting to a diver if you touch one. They have sail-like fins that are always erect and they sit motionless on the reef turning sideways to the surge from the surf above.
