This clown spider (Theridion grallator) just wants a kiss!
This species is often referred to as the “happy faced spider” because certain morphs have a pattern uncannily resembling a smiley face or a grinning clown face on their yellow body. They’re found in rainforests in Hawaii, and they’re just 5mm long. As the pattern may change according to what food the spider has eaten and as T. grallator is very small, hides during the day, and is thus not a significant prey item for any species of predator, it is more likely that the bizarre variety of patterns serves no significant adaptive purpose at all.
So then if no evillutionary purpose- then why? Maybe by an Intelligent Designer.
