Last week we asked you all to guess what kind of creature this is. Thanks to everyone who sent in your guesses! It's actually not a seahorse, or kelp. But we are so impressed — three of you knew it! You're obviously aqua-experts.

Chloe, age 11 of Illinois got it exactly:

I know what it's called! a Leafy Sea Dragon! YAY!

Josie from Texas, and another reader Erik also knew it was a seadragon. Congrats!

Seadragons are awesome, even though they're not real dragons. They come in two different varieties — the leafy seadragon and the weedy seadragon. They're around 18 inches long and they live in the sea south of Australia. Their crazy leafiness helps them camouflage with the kelp and seagrass around them, so bigger sea creatures can't see them and eat them. And they're just so cool looking!
