The sea snake is a particularly venomous variation on the typical viper that lives in warm, shallow seas. It typically attacks only if provoked. Even then it usually bites once and withdraws, waiting for the venom to take effect.

Combat

Poison (Ex): Bite, Fortitude save (DC 15); initial and secondary damage 1d6 temporary Constitution. A sea snake's poison is extraordinarily virulent. It has a +2 racial bonus on the poisons save DC.

Hold Breath (Ex): A sea snake can hold its breath for a number of rounds equal to 6 x its Constitution score before it risks drowning. For a typical sea snake, this is 66 rounds, or over 6 minutes.

Skills: A sea 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.

Improved Initiative: +4 on Initiative checks
