Sanguinivores

Sanguinivores are a group of organisms that primarily feed on blood. This dietary habit is distinct from carnivores, which consume animal tissue, and hematophagous organisms, which feed on blood but may also consume other substances. The term "sanguinivore" was coined by Dr. John W. Kimball in 1936 to describe the feeding habits of certain insects, particularly those in the order Diptera, such as mosquitoes and black flies.

The primary purpose of a sanguinivore's diet is to obtain nutrients such as amino acids, lipids, and minerals that are present in blood. Some sanguinivores, like mosquitoes, use blood as a protein source for their larvae, while others, like vampire bats, rely on blood for sustenance throughout their lives. The feeding behavior of sanguinivores varies widely; some, like mosquitoes, use proboscis to pierce the skin and suck blood, while others, like vampire bats, use their sharp teeth to bite through the skin and lap up blood.

Sanguinivores play a significant role in ecosystems, serving as both predators and prey. They help control populations of other organisms by feeding on their blood, and in turn, they are preyed upon by various animals, including birds, bats, and other insects. The study of sanguinivores is important for understanding the dynamics of ecosystems and the role of blood-feeding organisms in disease transmission, such as malaria and other vector-borne diseases.

Examples of sanguinivores include mosquitoes, black flies, horseflies, deerflies, vampire bats, leeches, and certain ticks. Each of these organisms has adapted unique methods to obtain and consume blood, reflecting the diversity of feeding strategies within the sanguinivore group.
