Mediterranean jumping spider (Saitis barbipes)

  • In New Zealand, researchers built an obstacle course for jumping spiders that they successfully completed. The maze included towers, platforms, moats (jumping spiders dislike being wet), and food containers. “Genuine cognition” is a term used to describe their capacity to plan and adapt when plans must change. It implies they consider things before they do anything.
  • Jumping spiders have excellent memories. Even after researchers had replaced it with an empty container, the spiders returned to the container that had previously held food (shown below).
  • Jumping spiders are site-fiduciary, which means that if they discover a suitable hunting or nesting spot, they will return there if driven away.
