The Lego 6190 Aquazone Shark's Crystal Cave is a set from 1996. It features a crystal cave with a hidden treasure, a shark submersible, and a mini-figure of a shark. The set is part of the Aquazone theme and it is missing 70001pb01 and (1) 44658.

This was a childs toy and was played with and shows some use. The booklet of instructions is in fair shape the front that shows set number is not great and the back has one of the corners taken off. So the set is average.
