Hematophagy (sometimes spelled haematophagy or hematophagia) is the practice of certain animals of feeding on blood (from the Greek words, haima "blood" and phagein "to eat"). Since blood is a fluid tissue rich in nutritious proteins and lipids that can be taken without enormous effort, hematophagy has evolved as a preferred form of feeding in many small animals such as worms and arthropods.
The chupacabra is a legendary cryptid rumored to inhabit parts of the Americas, with the first sightings reported in Puerto Rico. The name comes from the animal's reported habit of attacking and drinking the blood of livestock, especially goats.
