Today, there are mythic creatures that some people believed to be real, like the Loch Ness monster of Scotland and the Abominable Snowman in the Himalayas. A modern myth in the Americas is the chupacabra, a fanged beast with red, glowing eyes that kills goats and cattle by sucking their blood. Many sightings were reported in Puerto Rico in the 1980s, and have since spread to Latin America and southwestern US.
