Deep-sea animals take hide-and-seek to a whole new level! . Organisms like this bloodbelly comb jelly (Lampocteis cruentiventer) use red pigments to hide in the darkness of the deep sea. Red light is one of the first wavelengths of visible light to be absorbed by the ocean (at ~100 meters), so it appears black in the darkness of the deep. . Lighting at these depths is a subtle art. In order to actually see what is in the water and take high-quality images, MBARI engineers have equipped our ROV’s with multiple, high-powered lighting tools. The ROV Doc Ricketts has six 17,700 lumen LED lights and four 250 watt Incandescent lights. Just for comparison, the LED light bulb in your living room gives you 1,100 lumens and a typical light bulb runs from about 40-75 watts. The ROV Ventana uses six 400 watt HMI lamps and two 250 watt LED lamps—all used to light up and record the fantastic organisms that live in the absolute blackness of the deep sea. .
