This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Strix (Roman)
It was also known as strega or strigoi in various European countries. They differed from other vampire creatures in that they were thought of as living members of the community rather than the returning dead. The Strix was a bird of ill omen that fed on humans. It was believed that this animal was a terrifying creature that possessed a terrifying reputation.
These birds have long golden beaks and are known to suck the blood of their favorite prey. They have red-colored wings and black legs with clawed feet that helped them hunt their prey. Their eye were also different from owls as they were yellow and round without pupils. In classical literature, the strix is described as a large dark-colored bird with a large head and a rapacious beak.
