Does any animal have 32 brains?

No, the “32 brains” claim comes from leeches. Leeches have ~32 body segments, each with a local ganglion (nerve cluster) plus a small central brain. Ganglia coordinate reflexes but are not separate brains.

Real examples:

• Octopus: one central brain + large ganglia in each arm (often called 8 “mini-brains”) - effectively 9, not 32.
• Segmented worms and arthropods: chains of ganglia along a nerve cord, still one nervous system, not many brains.

So, no animal is known to have 32 brains.
