I think the top brain is the digestive system.
- dingo_bat 10y agoAh! Now it makes sense. Thanks!
- BioSciCreative 10y agoBased on what appears to be pattern in the "top brain" I believe it to be some kind of secretion or filtering organ. Based on my reference links above in the reply to bluenose69, I think it is the digestive gland. The stomach is actually much smaller and has a hollow opening at the very "top" of the octopus.
