Extension Investigation

If you need help scratching a mental itch, use the resources below:

  2. What are the believed prey of barreleyes and how do these prey relate to their "transparent dome" adaptation?
  3. Why is it important for barreleyes to be able to rotate their eyes?
  4. Does the barrel eye gain any advantages by having large numbers of cones and the visual pigment rhodopsin in their eyes?
