In Hawaii Octopus are referred to as “taco”, and is very popular to eat. While you could eat “taco” tacos, most people eat taco poke a marinated delicacy. I prefer my “taco”, on the reef.
While diving a while ago I noticed a snorkelor with a taco on her back. Check it out. Perhaps the taco had a predator stalking it and it was just hiding. I will never know as dont know the snorkeler.
