In Hawaii we call the octopus "tako" though that is a Japanese word. You will find Japanese words used here and there quite often in Hawaii. The Hawaiian word for octopus is one that I never even heard living here..I had to look it up! It's "he'e" which would be pronounced "hay-ay" as 'e' sound is 'a'.
