A bloodybelly comb jelly, the ctenophore, Lampocteis. MBARI scientist George Matsumoto described this animal for the first time in the zoological literature. Because animals that are red appear black underwater, scientists believe the bloodybellys red belly helps mask bioluminescent light from the prey it has swallowed.
Alexander Semenov is at it again with his fascinating study of underwater sea life through the photographic lens. Previously, we saw some of his colorful and vibrant jellyfish images in the series here. This time we take a look at his images from the Red Sea, a collection of photographs captured over the course of ten days of diving in the warm blue water.
