It Glows!

Recently an article called, "Crabs May Rely on Color to Tell Food from Poison" in The New York Times published by Sindya N. Bhanoo, states how two species of crabs have the capability to detect their food from poison. Majority of sea creatures are not able to detect colors in the water; however, these crabs can differentiate between two colors: blue and green. They are extremely sensitive to ultraviolet lights, which makes the latter possible. Under the sea, both corals and plankton produce light, and this can be dangerous for the sea animals because corals can be deadly to crabs. According to a biologist, from Duke University, once the plankton reaches the coral, it releases a blue glow. Also, simultaneously, the coral then generates a green luminosity. Therefore, the characteristic of these two species of crabs, truly validates the importance of Charles Darwin's theory of survival of the fittest. The researchers gathered all their data from oceans near the Bahamas. They even recorded and examined the crabs' eating habits. Researchers also took the initiative to capture eight of these crabs, and discovered how all their eyes were receptive to the ultraviolet lights. It amazes how there are so many different types of creatures, that we have not yet discovered nor distinguished. Humans always refer to themselves as the smartest creatures on Earth; but what us humans need to realize is that each organisms has their own unique talents which helps them survive and grow. This production of beautiful lights under the ocean, will without a doubt be a beautiful and a fabulous site to see.
