These Vampire creatures are from Mexico. They can be both Male and Female. They appear mostly human (sans their yellow eyes and fangs). Once created, The Tlahuelpuchi continues to live with it's human family (they will not harm them). In terms of their origins it is said that these vampires are curse (genetic). They prefer the blood of infants. They are also territorial creatures (hunting in pre-determined locations). They will not hunt in another Tlahuelpuchi's region. They have the power to remove their arms and legs from their body (although why they do this is unclear).
