Can Sponges “Think” Using Light?

The video explores the unique biology of sponges, simple animals without a nervous system, and their potential use of light to transmit information. Sponges may use bioluminescent cells, glass-like spicules, and cryptochromes to create a sensory system, acting as a quasi-nervous system. This hypothesis, though untested, suggests sponges process environmental information in a way similar to more complex organisms.
