"A new species of leech, discovered by an international team of scientists, has a preference for living up noses. Researchers say the leech can enter the body orifices of people and animals to attach itself to mucous membranes. They have called the new blood-sucking species Tyrannobdella rex which means tyrant leech king. The creature was first discovered in 2007 in Peru when a specimen was plucked from the nose of a girl who had been bathing in a river. The creature lives in the remote parts of the Upper Amazon and has a "particularly unpleasant habit of infesting humans", the scientists say. Studies also revealed that it had a preference for living up noses. " http://news.bbc.co.uk/2/hi/science/nature/8623332.stm A Peruvian leech that lives in noses? Sounds like an animal with a serious cocaine addiction to me.
