This is mizudako from Hokkaido, Japan.
I was reading from Wikipedia. We call it leg but Americans say as arm.
And we think it as head is actually body. Head is just above of arm.
Octopus is a same group of squid. But Squid have 12 arms and octopus have 8.
Octopus is high intelligence animal. They can see colors, can understand shapes and can study.
Octopus is very popular now because of World Cup. A German Octopus can hit which team wins.
Their life span is very short. Most of octopus live a year.
I make carpaccio or tiradito with this products.
