Constrict (Ex): On a successful grapple check, a dung snake deals 1d3+4 points of damage.

Improved Grab (Ex): To use this ability, a dung snake must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can constrict.

Environmental Adaptation (Ex): Dung snakes can exude a protective slime around themselves, protecting them from non-lethal cold damage.

Skills: A snake has a +4 racial bonus on Hide, Listen, and Spot cheeks and a +8 racial bonus on Balance and Climb checks. A snake can always choose to take 10 on a Climb check, even if rushed or threatened. A snake uses either its Strength modifier or its Dexterity modifier for Climb checks, whichever is higher.

A dung snake 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.

The dung snake kills by holding its prey underwater while constricting.
