Did you know? This animal has 32 brains 10 stomachs

The interior anatomy of a leech is divided into 32 segments, each with its own brain. Leech is an annelid. They have segments. However, unlike other annelids, the leech’s exterior and internal segmentation do not coincide. When the interior body is inspected, it is clear that the body is divided into 32 pieces or segments, each with its own brain.

These are not separate brains, but rather the same brain divided into 32 segments according to Leech’s theory. Each segment has its own neural ganglia that are connected to the next. Thus, physically, it is the same one brain that exists in 32 parts across the body.

Habitat

Leeches are mostly surface dwellers in fresh water, moving above rather than through the river bed. They are particularly frequent in warm, sheltered shallow places where currents are limited and plants, stones, and detritus give protection.

Life cycle and lifespan 

It generally takes about 2 weeks for the eggs to hatch into little leeches—about 5 per cocoon. They become reproductively mature in about a year. A leech can live from 2–8 years.
