El Chupacabra is a legendary creature from Latin American folklore, said to attack livestock—especially goats—and drain their blood. Descriptions vary, but it’s often portrayed as a reptilian or dog-like beast with grayish, leathery skin, sharp claws, spines or quills running down its back, and glowing red eyes. First reported in Puerto Rico in the 1990s, it quickly became one of the most famous modern cryptids, linked to mysterious animal deaths across the Americas.
