In regards to clotting under water I see no reason that it would not considering that human blood will also clot under water.

The myth that those that cut their wrists will bleed to death by running water over the wounds it just that -- a myth. They may bleed to death depending on the extent of the slashing, but blood can still clot under water.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
