According to the legends, the Chupacabra is said to be a creature that preys on livestock, particularly goats and other small animals, by draining their blood. Descriptions of the creature vary, but it's often portrayed as having reptilian or alien-like features with sharp fangs and claws.
It's important to note that there is no scientific evidence supporting the existence of the Chupacabra, and many reported cases of livestock deaths attributed to the Chupacabra have been found to have more plausible explanations, such as natural predation or disease.
