Well, the first thing that you could try adding to your search is "lenticular," as that is what those types of puzzles are called. Without a description of what was in the image beyond the term "shark," (number of pieces, number of sharks, etc.) I have no way of knowing which puzzle you are looking for. I did find this one called "Open Jaws" https://www.amazon.com/dp/B087Y2Y7C3?lv=shuf&channelId=500&plpRedirect=mhFallback and this one called "Shark Waters" https://www.ebay.com/itm/116646508238 . There is also one called "Dangerous Waters" from 2004. https://www.etsy.com/listing/1732675835/new-dangerous-waters-2004-shark-visual
