Alligators are stalking the flooded waters of New Orleans and rescuers fear that they will eat the bodies of Hurricane Katrina's victims.
Michael Rieger, of the federal emergency agency, said patrol boat crews had seen many alligators in the floodwaters.
Authorities have just started the operation to recover what could be thousands of bodies in the floodwaters, on the streets and trapped in homes.
Rieger said: "There are a lot of people who are never going to be found. There are a lot of alligators in the water, and alligators love that type of stuff."
