Original Note:
Sea urchins, like their close relatives the sea stars (starfish), don't technically have eyes. Instead, the ball-like invertebrates detect light striking their spines and compare the beams intensities to get a sense of their surroundings. https://www.nationalgeographic.com/science/article/100205-sea-urchins-spines-eyes
