Guest Post: Hawaiian happy face spider

The Hawaiian happy face spider (Theridion grallator) has naturally evolved a multitude of patterns in order to confused predators – and many of them strangely enough resemble a yellow smiley face. Scientists believe that having individuals with varying patterns has helped the species avoid predators such as forest birds, but no one’s quite sure why the smiley faces have been so popular.
