The stern jumping spider is a jumping spider from Australia. It has eight eyes, and the two big ones at the front look straight at you like car headlights. It does not catch food in a web. It sneaks up and pounces.

Fun fact: spiders are not insects. Insects have six legs, spiders have eight. Everyone calls them bugs anyway!
