I had a few sets of shark teeth years ago, as well as one large one on a necklace, all of which I've got from different aquariums, I don't know where they've gone but today I finally managed to get some new ones! I'm not 100% what kind of shark they're from, probably Reef Shark but it might be a mixture of a few. I fell in love with the Shark plushie as soon as I saw it so I decided to get that too, it's soooooo cute! I might make it into a Black Tipped Reef Shark tho, they're one of my favorite kinds :D

The plush is a premier edition large shark plush by Ark Toys LTD
Doesn't say where the teeth came from, the box just says 'Sharks teeth'
