Gunner and Delta are two best friends who love hanging out together and giving each other sweet little kisses.

Their friendship is so adorable and pure, and they don’t mind that they’re quite a miss-matched pair, to say the least.

You see, Gunner happens to be a  golden retriever, and Delta is a dolphin!

Delta lives at the Dolphin Research Centre in Florida, which is where the pair first met.

The unusual friends first met when Gunner was just eight weeks old and Delta was four years old.

The pair have been best friends ever since, and recently, a picture of the two cuties went viral on Twitter.

Their unexpected friendship has completely melted everyone’s hearts, and people are extra smitten by the fact that they like to give each other little kisses.

Delta presents his pointy little nose for some  puppy kisses, and Gunner happily licks his BFF and shows how much he loves this strange-looking water-puppy.

The two friends are so ridiculously cute together, and we just can’t get over how magical their friendship is.

Online, people can barely handle this level of adorableness.
