Nudibranch

I subscribe to National Geographic's photo of the day and this is the picture they put up today.
Now my first thought was what the heck is National Geographic doing putting doctored photos up. I thought they had more class than that! But it is an actual real animal. It's called a Nudibranch. They look similar to sea slugs however there gills are exposed which separates them. Random, but cool huh? Look up more info on them on Wikipedia they are very interesting creatures.
