The box jellyfish is able to see through four sets of eyes!


Box Jellyfish

The box jellyfish is able to see through four sets of eyes, one at the center of each side of the bell, each set clustered in a club-shaped structure called the rhopalium. Each set actually consists of six eyes: four simple pigmented pits with photoreceptors and two complex camera eyes, one pointing up and one pointing down, each with a cornea, lens, and retina. Scientists are not sure how the animal processes the visual information since it has no brain. Certainly, God designed this “primitive” animal with amazing capabilities that defy any evolutionary explanation.


  • Box jellyfish are pale blue, transparent, and bell or cube shaped with four distinct sides.
  • The box jellyfish has a group of 15 tentacles at each corner of its body, with up to 5,000 stinging cells each.
