Obviously well fed, most likely from pets left behind

look at the head

definitely a pit viper species from that arrow shaped head and probably poisonous

I guess there isn't a lot of swimming done in ponds and rivers down South.

What animal is directly above the Water Mocs on the food chain? What keeps them in check? (I hope something does).

Yep. It's called a 12 guage shotgun!

An ugly and agressive animal with no natural preditor? Not even PETA would try so save these things.

Water Mocs or Snowstorms..... I'll take the snow.

Being from Mississippi, I am realy familar with these guys! They hang over the water in Willow trees and drop in-sometimes into the boat with you-when disturbed! they are mean evil creatures, and yes I have swam in lakes and streams all over the south but you gotta watch out for them!
