Cold Tolerant (Ex): A giant beaver's insulating fat grants it a +2 racial bonus on saving throws made against cold attacks and environmental conditions.

Hold Breath (Ex): A giant beaver can hold its breath for a number of rounds equal to 6 x its Constitution score before it risks drowning.

Natural Lumberjack (Ex): A giant beaver ignores the hardness of wooden objects with its bite attack.

Skills: A giant beaver has a +16 racial bonus on Craft (dambuilding) checks. A dire beaver has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.

Like their lesser cousins, giant beavers will generally take to the water if danger comes their way.
