The Happy Face Spider
This spider reminds of the Joker from Batman
- "Now I'm always smiling..." This happy face
spider is found only on the islands of Oahu, Molokai, Maui, and
Hawaii, and is known for the unique patterns that decorate its
pale abdomen. Scientists believe Theridion grallator may have
developed its distinctive markings to discourage birds from
eating it. More amusing pictures here.
