Big mystery...little mystery.People have known about the giant squid for centuries without ever seeing one alive. But sometimes scientists don't know Don't know (DK, DKed) "Don't know the trade." A Street expression used whenever one party lacks knowledge of a trade or receives conflicting instructions from the other party. a species exists at all until they stumble upon it accidentally! Take the mysterious new creature below. Biologist James Hunt This article is about the racing driver. For other people named James Hunt, see James Hunt (disambiguation). James Simon Wallis Hunt (b. 29 August 1947, Belmont, Surrey – d. videotaped it swimming 6.5 km (4 mi) below the ocean's surface in an undersea trench near Japan. Hunt was exploring in the Shinkai 6500, the deepest-diving crew-carrying submersible submersible, small, mobile undersea research vessel capable of functioning in the ocean depths. Development of a great variety of submersibles during the later 1950s and 1960s came about as a result of improved technology and in response to a demonstrated need for in the world. The newly discovered species is a marine worm Any worm that lives in a marine environment is considered a marine worm. Marine worms are found in several different phyla, including the Platyhelminthes, Nematoda, Annelida, Chaetognatha, Hemichordata, etc. Some of them are segmented and some of them are not. about 12 cm (5 in) long. Like the giant squid, it's an invertebrate--an animal without a backbone. It swims with the help of glassy, paddle-shaped bristles. Hunt's team tried to catch the worm but couldn't. To collect an animal, the pilot steers the Shinkai so an open chamber on the sub passes over the critter. Then, the chamber seals, trapping the animal inside. At a depth of 6.5 km, the ocean is cold, totally quiet, and black as soot soot, black or dull brown deposit of fine powder resulting from incomplete combustion of fuel of high carbon content, e.g., coal, wood, and oil. It consists chiefly of amorphous carbon and tarry substances that cause it to adhere to surfaces. . How does this worm survive in such an environment? "We don't have a clue," says Hunt. "There's so much yet to be learned about our planet that it goes beyond description. The next step for my team is to dive again, find and collect another worm, and try to answer our questions." |
