According to the USDA Nutrient Database (2007), cooked octopus contains approximately 139 calories per three ounce portion, and is a source of vitamin B3, B12, potassium, phosphorus, and selenium. For those that actually cook it, care must be taken to boil the octopus properly, to rid it of slime, smell, and residual ink. So, why do people eat live octopus when so much care needs to be given when cooking it? YUCK!
