Discussion questions

Talk about it

A cone snail can't chase a fish, so it uses a hollow, harpoon-shaped tooth to strike and hold prey, then reels it in. A slow body plus one specialized structure equals a successful hunter.

  1. How does a slow snail catch a fast-swimming fish?
  2. What structure does the cone snail use to strike?
  3. Why is one special tool enough for a hunter that can't chase?
