Discussion questions

Talk about it

A male jumping spider taps out vibrations and flashes colors to tell a female who he is. She senses the vibrations through her legs and 'reads' the display. Animals use senses to send and receive signals -- a kind of language without words.

  1. How does the male spider send his message?
  2. How does the female spider receive and 'read' that message?
  3. Why is sending the right signal so important for the male?
