One Fish, Two Fish, Red Fish? or Black Fish?

The close light of the ROV reveals this Big Eye’s red color. Normally, at these depths, red appears black– an effective camouflage.

Light is interesting... in water, particles, such as detritus and plankton, and the water itself, get in the way and block or absorb the wavelengths. Since red has low energy, it gets interfered with quickly. The shorter, higher-energy blue wavelengths can reach down farther. Now, think back to our Big Eye example. He’s red. However, at depth he looks black and is camouflaged against the background of dark rocks and shadows.
