“The Aquasharks subtheme consisted of relatively few sets - I don't have a problem with any of them, I just wanted more. The same could be said for Shark's Crystal Cave - I love everything that is provided, I just wish there was more of it (primarily a larger base). That... More really speaks to the appeal of the set, it looks great and it's a ton of fun to play with. A point was recently made about these Aquazone sets being forgotten and often overlooked. This is a shame as I believe this set is easily one of the high points in all the history of aquatic themes.”

Brickipedia

“Shark's Crystal Cave is the largest Aquasharks set and one of the largest Aquazone sets. It is composed of a large ship, which is the Aquasharks' largest vehicle, and their base. The vehicle is similar to the Aquashark Barracuda. It has two cockpits. The cockpit on the... More bottom has a Shark-Face windscreen.”
