Bioluminescence Bioluminescence is the term used to describe light produced by living things. There are several different types of organisms that can make light, including fungi, bacteria, insects, and fish. Dinoflagellates are a special type of marine algae that produce light. They only make light when disturbed by an object moving through the water. Examples of light-producing marine life can be seen along coasts across the globe when the night sky is at its darkest. People most often describe these viewings as "glowing waters" or "red and blue waves." Scientists believe these creatures emit light to ward off predators, attract prey, and/or communicate. Passagee 2 adapted from Living Lights: a Popular Account of Phosphorescent Animals and Vegetables by Charles Frederick Holder In 1868 or 1869, I was exploring the reefs near Port Louis. It was there that I witnessed one of the most singular sights it is possible to believe. My crew gently moved my boat over the reefs, so that I could see any object in the water. As the boat crossed over the reef into deep water, I was amazed to find the water alive with hundreds of millions of little creatures. The little creatures 3 Which statement best describes the most important ideas conveyed by the passages?
