Monsters in Scotland

　　It is said that Nessie is a lake monster inhabiting Loch Ness in Scotland. This monster is one of the best­known cryptids (未知生物) studied by cryptology (密码学). Popular belief and interest in the animal has fluctuated over the years since it came to the world's attention in 1933.Evidence of its existence is largely anecdotal (轶闻趣事的), with minimal, and much disputed, photographic material and sonar reading, there has not been any physical evidence (skeletal remains, capture of a live animal, definitive tissue samples or spoor) uncovered as of 2008.

　　A similar loch monster named Morag is reported to live in Loch Mora, Scotland.After Nessie herself, Morag is among the best known of Scodand's legendary monsters.
