GIANT SEA SNAIL

Such a creature, readers may remember, was encountered by Dr Dolittle, the man who could communicate with animals in the books of Hugh Lofting.  However, such a creature has been reported in reality.  It was reported in the Baltic Sea in the 16th Century.

Certain features apart from size distinguished it from the average snail.  It had paws and there were eyes on either side of its head.

If you own a French restaurant and see this as a possible source of food, I would point out that it has not been seen in modern times, so I would advise against a hunting expedition.  It has not been seen in recently and, even if a small population still exists, such an expedition would not alone be unprofitable, it would be execrable.
