LOCH NESS

a long, narrow and deep lake in the northern Highlands of Scotland. It is famous for the Loch Ness monster , also known informally as Nessie . The monster is thought by some people to be a large animal like a dinosaur (= an animal that lived millions of years ago) that spends most of its time underwater. Many people claim to have seen it, and there is a special Loch Ness Monster Exhibition Centre for tourists on the edge of the lake. However several scientific investigations have failed to find any evidence that it exists.
