Ten seconds and boom, the leeches are ready to feed on your blood. Leeches were once used to treat headaches, compression and they still are a significant part of the surgery. But the question is how they are bred?

What Is A Leech?

A leech is neither a slug, a reptile, nor an insect. An invertebrate animal belonging to the phylum Annelida, a zoological classification that includes over 15,000 species of segmented bristle worms and 650 species of Hirudinea leeches. Not all leeches feed on blood, and not all bloodsucking leeches feed on human blood. They’ve evolved, and many leeches now live in Camel’s nose, while others feed on bats. The Giant Amazon leech can reach 45 cm in length and feeds by injecting a 10-centimeter straw-like structure into its prey.


Organs Of The Leech

These are freshwater, blood-sucking, multisegmental annelids with ten stomachs, 32 brains, nine pairs of testicles, and teeth that leave a mark if a leech bites. These leeches inject a local anaesthetic into the host, preventing them from recognising their presence for a short time before tucking in. This is why a leech bite feels like a sensation rather than a scrape.

Uses Of The Leech

Blood may get trapped in certain operations that involve rejoining tiny blood vessels, such as reattaching an amputated finger, hand, or lip, or reconstructing a breast, leeches are very helpful in those surgeries. A leech may mean the difference between success and failure in a reconstruction or reattachment. . The leech is a straightforward animal in many respects, but science has yet to improve its anaesthetic and anticoagulant.
