Question

Which animal has 32 brains, 300 teeth, and 5 pairs of eyes?

Answer 1

Leech:

1. The interior structure of a leech is divided into 32 different segments, each of which has its own brain.
2. An annelid is a type of worm. They are divided into segments.
3. However, unlike most annelids, the exterior and internal segmentation of the leech do not match.
4. When looking at the interior body, it can be seen that the body is divided into 32 pieces or segments, each with its own brain.
5. These are not separate brains, but the single brain that has been split into 32 segments in the manner of a leech.
6. Each segment has its own neural ganglia, which are connected to the next.
7. In other words, anatomically speaking, it is the same brain that exists in 32 segments across the body.
8. Physiologically, one ganglion regulates the other.
