For the purposes of determining a creature's hit points, a distinction is made between the creature's hit dice (HD), which indicates the creature's ability to hit, and the creature's mass, which can vary greatly with respect to HD. For example, a cockatrice has 5 HD and weighs 98 lbs., while a moose also has 5 HD and weighs 1,220 lbs., or more. Therefore, because of its mass, and although a cockatrice is still a dangerous creature, a moose will have more hit points than a cockatrice.

How much more is indicated by the table shown.
