Discussion questions

Talk about it

A jumping spider's big eyes send detailed information to its brain. It uses that information to judge distance and time its jump — sensing, then acting.

  1. What sense does the jumping spider rely on most to hunt?
  2. How does the spider use what it sees to plan its jump?
  3. Why is good information important before an animal acts?
