I'll be the first to admit that sea anemone aren't exactly cute- but they are darn mesmerising! They inhabit tropical oceans and sea floors and in some ways are like the flora of the sea (though technically they aren't plants).
They remind me of complex computer produced fractals. The fact that they are so intricate and diverse I think that they're one of the most stunning natural things on Earth.
Check out the rest of the images below- I have included a cute starfish hidden in there somewhere for a bit of an extra "cute" factor~ why? Cos I found it and thought it was sweet!
