   Can a jellyfish see a cone?

   • And, as Garm found, the jellyfish is beautifully adapted to keep an eye (or four) on the canopy. By analysing the upper lens eye, Garm found that it has a visual field of around 95 to 100 degrees (which is roughly what ours is). Imagine a cone sitting on top of the eye, with an angle of 95 degrees – the eye can see everything within the cone.
