Blood consumption

Blood consumption is the habit of feeding on the blood of another being for sustenance or other ends. Though blood, especially congealed blood, is used in dishes worldwide, the most common perception of blood consumption is bloodsucking, the (usually parasitic) drawing of blood from a live victim. Several animals, mostly insects, are primarily or solely bloodsuckers. Other notable bloodsuckers include vampire bats and leeches.
