Tazmara swings her heavy pick under the canoe. She clearly hits something, but the canoe prevents her from observing the effect other than the dissapearance of both claws. The wolf and the man jump into the water to join the fight, but achieve nothing but raising some mud from the bottom.

Everyone, including the "crab", has cover from the upside-down canoe. Unless you do something about it, only three of you (e.g. those already in the water) can fight the "crab" at the same time. Funny thing that a longsword has -2 to hit underwater and deals only half damage, as do other slashing and bludgeoning weapons, but the pick, also a swung weapon, has no penalty, because it deals piercing damage and damage type is what Pathfinder uses to differentiate. I think I won't houserule anything here, so just making you know.
