Problem with Immigrant in Birmingham
This story I have borrowed from Boundary Post - the newsletter of the BCN society. My thanks to Brenda Ward, editor.
It grows to the size of a dustbin lid, will eat anything in its path and is normally found in the Mississippi.
It is an Alligator Snapping Turtle.
This creature, or one very like it, was fished (is that the correct term for retrieving a reptile?) out of the canal at Broad Street, Birmingham.
