I've found that the seasnake's behavior doesn't use it's full compat potentioal. the seasnake best performs in combat when it's head ignores the preay, and passes by or circles it, allowing it's body to "broadside" the prey not unlike battleships of old. Also, when running through territory filled with swarms of strong and dangerous predators, it's tendancy to try to turn tail actually gets it killed when simply jinking around the threat coming in from the front would have saved it's life. But, as far as I can tell, the seasnake is quite powerful as it is.
