Scientists have discovered new and amazing creatures of the deep sea. These are several species of worm capable of launching small "light bombs" around. Something that can be very useful when fleeing from predators.
The researchers made their discovery on the coasts of the Philippines and also in the U.S. and Mexico. A total of seven new species have been introduced at the same time, five of which have the rare ability to throw around little spheres that, when separated from her body begin to glow in a bright green. It is, as stated in their article, further evidence (the last for now) of how little we still know about the inhabitants of the deep ocean.
Familiarly called "green bombers", new species of worm are between 18 and 93 millimeters. And they were located through the use of remotely operated mini-submarines at depths ranging between 1,800 and 3,700 meters. The first species has been described bombiviridis Swima call due to its ability to drop bombs mentioned light.
Worms in the water move through several rows of thick hair that used like fins or oars. "The water depths between 1,000 and 4,000 meters explains Greg Rouse, study co-forming the largest habitat on Earth and also the least explored."
All species have found a series of elaborate appendages on the head. Five of them are equipped with mechanisms of luminescence. The "bombs" are made of a dense fluid in turn is released by the animal, shines for a few seconds and then fades slowly.
Because mini-submarine's own lights, scientists were unable to obtain images of the phenomenon in the natural environment, but they did after capture in the laboratory. And although they assume that light pumps are part of an elaborate defense mechanism, say further studies are needed to understand the process completely.
