Giant squids live between 1,000 and 3,800 feet in the ocean. With a dry dive suit, a scuba tank, gloves, and so on, divers can reach depths of around 1000 feet. Without scuba gear people can safely dive a maximum of 60 feet without feeling the negative risks associated with diving beyond the limit.
