Heart-Shaped Clams Channel Sunlight Using Fiber Optic-Like Structures, Says Study
Researchers have discovered a biological adaptation in heart cockles (Corculum cardissa), a species of bivalve found in the Indian and Pacific Oceans. These clams possess unique structures in their shells that act similarly to fibre optics, guiding sunlight to symbiotic algae living within them. This allows the clams to provide their algae with the necessary…
