Tako-san is a very clever octopus.
She can understand what I want to say from just my gestures.
Somehow she can even read and write characters.
She can also change the patterns on her body.
She has learned to change her patterns into pictures and characters.
"I want to watch a movie on tako-san."
The patterns on her body changed.
This page proves that the Takos can be physically separated, at least for some time.
