Another question I asked made me realize that English has many names for mythical beings. Many of these can refer to both a historical myth or superstition as well as a more modern definition (in fiction, gaming, movies, etc.), but most of them clearly refer to a particular type of mythical creature.
Mythical creatures I can think of would include the following. Do these have direct translations in Spanish? If not, what words for mythical beings exist in Spanish and what types of creatures do they refer to?
