1. Camera eyes in cubozoan jellyfish
   On each of the four club-like extensions (rhopalia) near the base of the cubozoan jellyfish bell there are two camera-eyes, one pointing upwards and the other downwards.

2. Vision in echinoderms
   Among brittlestars and sea urchins we find visual systems that in some ways rival the arthropods in the form of compound eye-like structures.

3. Compound eyes in arthropods
   It is clear that amongst the arthropods as a whole the compound eye has evolved at least twice, and possibly even more times.

4. Camera-like eyes in arthropods
   Arthropods are famous for their compound eyes, but some groups have had a fair crack at evolving the optically superior camera eye…

5. Camera eyes of cephalopods
   The remarkable similarity between the camera eyes of cephalopods and vertebrates is one of the best-known examples of evolutionary convergence.

6. Octopus and other cephalopods: convergence with vertebrates
   What could be more different from us than the alien-like octopus? Hold on. Look it in the eye and think again.

7. Camera eyes in vertebrates, cephalopods and other animals
   Camera eyes are superb optical devices, so it is not surprising that they have evolved several times. But why, of all animals, in the brainless jellyfish? Or for that matter in a slow-moving snail?
