Sun-Shade Spade-Arm!
The male fiddler crabs have a huge right claw (that looks like a fiddle and so the animal gets that name), which they use to display and attract females. Except for this purpose, this claw is believed to have no other use.
However, in this picture, where the fiddler crab makes its display to shoo off opponents, this frame appears as though it is using the arm as a sun-shade, though it is obviously not using it so!
