Eco-Friendly Wildlife Resort?

Question

I was watching the travel channel the other day, and I saw this wildlife resort... by that I mean that their pools were all natural, and teeming with wildlife such as seaturtles that you could swim with. I've searched for at least two hours online, and I'm begging someone to help. I think they said it was only a few miles outside either Cozumel or Cancun. I'm looking to go here for my honeymoon, and I am hoping someone can help. PLEASE?! :D

Answer 2

Possibly Excaret? But I believe this is man made eco park not 'natural pools' unsure on that one
