Rainforest

With its iridescent turquoise markings and four pairs of eyes, this jumping spider (Thania bhamoensis) is well-equipped to recognize and assess members of its own species. The spider’s large central eyes are responsible for acute vision and allow it to differentiate between potential mates and rivals. (Among other differences, females tend to be greener, while males are bluer.) Meanwhile, the spider’s three smaller pairs of eyes can detect movement on all sides, which comes in handy both when fighting off rivals and being on the lookout for potential prey.
