Imagine the gut-dropping moment your phone slips off the edge of the boat, and disappears to the bottom of the ocean.

That is what Teressa Cee, a Miami Heat dancer, faced while boating with friends and swimming with dolphins off the coast of the Bahamas.

Lucky for the young lady, Cacique, a very smart little dolphin, was nearby to come to the rescue.

Once Cacique saw the trouble, he dove to the bottom of the ocean, retrieved the lost phone and returned it to the grateful owner.

"We were filming on this floating platform in the middle of the Atlantic Ocean. So, against my better judgment I asked someone to hold my phone for me and he accidentally dropped my phone into water and it sank to the bottom," Cee wrote on Instagram.

"Cacique, the dolphin, actually retrieved my phone and brought it back up to me. Cutest thing ever!" she added.

The phone suffered, maybe obviously, catastrophic water damage and won't be working again, but thanks to Cacique, at least it won't be lost to the sea!
