Leeches, those bloodsucking creatures, have a fascinating anatomy. A common misconception is that they possess 32 brains and 10 stomachs. Let’s explore the truth behind these claims.

Brain: Leeches have a single brain, but it is divided into 32 segments, each with its own cluster of nerve cells called ganglia. These ganglia are interconnected and control the functions of their respective segments. While anatomically, it’s one brain, the physiological functioning across 32 segments gives the impression of multiple brains.

Stomach: Leeches do indeed have 10 stomachs. This complex digestive system allows them to store large amounts of blood, enabling them to survive for extended periods without feeding.

Other Interesting Features:

  • Teeth: Leeches also have hundreds of tiny teeth that help them latch onto their host and draw blood.
  • Eyes: They possess five pairs of eyes, although their vision is limited.
  • Testicles: Leeches are hermaphrodites, meaning they have both male and female reproductive organs, including nine pairs of testicles.
  • Anticoagulant Properties: Leeches are famous for their anticoagulant saliva, which prevents blood clotting. This property has been exploited in medicine to promote healing and blood circulation.

Bloodsucking Behaviour:

Leeches are freshwater worms known for their bloodsucking habits. They attach to their host using their suckers and teeth. Once they have had their fill, they detach and fall off. However, if a leech attaches internally, such as inside the nose, medical intervention might be necessary to remove it.
