Hawaiian Happy-face Spider
A tiny Hawaiian spider with markings on its abdomen that resemble a smiling face. It is endemic to the rainforests of four Hawaiian islands.
Did You Know?
The smiley-face pattern is thought to confuse predators by disrupting recognition of the spider shape.
Round-bodied Scydmaenine
A minute, convex rove beetle of the subfamily Scydmaeninae with a distinctively constricted waist between thorax and abdomen. It is a specialized predator of armored mites in forest soil.
Did You Know?
This tiny beetle has evolved specialized mandibles that can crack open the heavily armored shells of oribatid mites, prey that most other predators cannot exploit.
