Does anyone know if there where any d20 stats done for sea snakes from 1st edition D&D? Or do you think it would be easy just to use the various viper stats for different sizes as per the 3.5 d20 monster book and apply the aquatic subtype? Do they have any special abilities other than a common snake you think? Thought sea snakes in real life have a deadlier poison than the land varierties (maybe an ability focus for +2 DC or such).
