Pocket sharks are worlds rarest find

New York: Ever heard of a five-inch-long shark? That's a very rare species discovered recently -- and if you ever spotted one, you'd only be the third person to ever do so. The common name of this species is the "pocket shark", though its scientific name is Mollisquama sp, said a new study. While it is small enough to fit in your pocket, it's dubbed "pocket" because of the distinctive orifice behind its pectoral fin -- one of many physiological features scientists hope to better understand. The dead specimen spent more than three years in a giant freezer waiting to be identified. It turned out to be only the second of its species ever seen.
