The Lake Sturgeon is a primitive fish, with a cartilaginous skeleton. It has 5 rows of large, prominent, bony plates (or scutes) on its body. A small aperture, the spiracle, is present between the eye and the upper corner of the gill cover. The region from the anus to the tail fin is thick and not entirely covered with bony plates. Lake Sturgeon have a flattened snout, with large, fleshy barbels and a protractile mouth located under the head. The lower lip has 2 slightly papillose lobes. The Lake Sturgeon is Minnesota's largest fish and can reach a total length of 2 m (6.6 ft.) and weigh over 45 kg (99 lbs.). They kind of look like a freshwater shark?
So Hard Scrabble. This is a cipher, meaning you need a key to solve what the letters stand for? I am sure you spell a solution that will work for you... It would be fun to catch one of these fish someday, so cool looking.
