- Bioluminescence is found in many marine organisms: bacteria, algae, jellyfish, worms, crustaceans, sea stars, fish, and sharks to name just a few.

Oct 30, 2024 · Sources of light are things that generate or reflect light such that they illuminate environments. This includes the Sun which is massively responsible for most light on our planet and across our solar system. There are also many natural and human-made sources of light. All (75) Nature (6) Space (17) Bioluminescent Organisms (19) Human-made (33 ...
Some fish dangle a lighted lure in front of their mouths to attract prey, while some squid shoot out bioluminescent liquid, instead of ink, to confuse their predators. Worms and tiny crustaceans also use bioluminescence to attract mates.
Nov 11, 2024 · Light in the ocean travels at a velocity equal to the velocity of light in a vacuum divided by the index of refraction (n), which is typically n = 1.33. Hence the velocity in water is about 2.25 ×108 m/s. Because light travels slower in water than in air, some light is reflected at the sea surface. For light shining straight down on the sea ...
Similar to the atmosphere, light attenuation in the ocean is dependent on the concentration of "stuff" in the water. For example, light can shine all the water to the bottom of clear Caribbean waters, whereas you can barely see your hand beneath the surface in muddy river waters.
Climate, winds, and major ocean currents are ultimately dependent on solar radiation reaching the Earth and heating different areas to different degrees. Sunlight warms the surface water where much oceanic life lives. Solar radiation provides light for photosynthesis, which supports the entire ocean ecosystem. The energy reaching Earth from the ...
1 day ago · Some years ago I was returning to my island house in Maine, under a dark night sky, and I noticed that the wake of the boat was glowing. As far as I could tell, it was bluish in color. That was my first experience with bioluminescence. Later, I discovered that I could create that same oceanic glow simply by waving a stick or paddle in the water.
Marine worms, sea cucumbers, sea stars and many types of phytoplankton also emit light. Bioluminescence involves a chemical reaction inside the animal’s cells. For some animals, those cells are located in a special light organ called a photophore that can look like a spotlight.
