What organisms are found in the Aphotic zone?

Examples of aphotic zone animals include algae, anemones, anglerfish, arrow worm, cookie-cutter shark, copepods, crabs and other crustaceans, ctenophores, dinoflagellates, fangtooth, lanternfish (Myctophids), mussels, nudibranchs, some squid (like the vampire squid), segmented worms, siphonophores, swallower fish.

What is the relationship between light and depth?

The intensity of sunlight decreases rapidly with depth. The depth of the water not only affects the colors of light that are noticeable underwater, it also affects the intensity, or amount of light. Within the first 10 m, water absorbs more than 50 percent of the visible light energy (Fig.

Does water absorb color?

The density of water also affects colors. Water absorbs colors of the light spectrum as light rays travel through the water, and this is called absorption. Red is the first color absorbed, followed by orange, yellow, green, blue, indigo, and violet.

What happens when water reflects light?

Refraction: When light travels from one transparent medium (air) to another transparent medium (water), the speed of the light slows down and when it hits water it changes its direction slightly. This change in the direction of light is known as refraction of light.

Does ice reflect light better than water?

In fact ice is slightly less reflective than water. The slightly lower refractive index of ice will cause a slightly lower reflectivity. In both cases the reflectivity is about 0.05 i.e. at an air/water or air/ice surface about 5% of the light is reflected.

Does dust increase albedo?

Albedo – reflections of solar radiation from surfaces on the Earth – makes exact predictions difficult. If e.g. the polar icecap melts, the albedo will be significantly reduced. Dust particles in the air may reflect light, but settled on e.g. glaciers, soot and dust particles may absorb heat and increase melting.
