I like its eyes: two black dots, nonreflective light-trappers. Utterly determined eyes, doubt-free, unselfconscious. Frightening eyes if they happen to be looking at you and you're small enough to be dinner. The same eyes a man probably sees on an alligator before it drags him down and shakes the air out of his lungs and leaves him to rot a little in the murk, to be tenderized properly before he becomes a meal.
