This absorbs almost all of the incoming light, and any remaining light that scatters sideways is absorbed by neighbouring granules. Altogether, the absorption of light is 99.5% efficient, a fact that makes photographing this fish in its natural habitat very difficult.
This effectively consumes almost all of the incoming light, and any remaining light that scatters laterally is absorbed by adjacent granules. Overall, the absorption of light reaches 99.5% efficiency, a fact that makes photographing this fish in its natural environment extremely challenging.
