Many people fervently believe in angels. Others are unconvinced and scoff at the idea. But if you look closely in the ocean from the equator to both poles you just might see tiny angels using their wings to propel themselves through the water. They are mesmerizing and seemingly quite gentle and peaceful. These graceful, transparent and red creatures are called sea angels -- and looks can be deceiving.

If you have ever watched the television show Supernatural then you may have gathered that angels are not the peaceful beings of light that they are cracked up to be. The same could be said of sea angels. They are actually a form of sea slug that viciously feed on other forms of gastropods by expelling hooks and tentacles from their mouths suddenly.

The sea angels are gelatinous red and red-brown portions of their insides visible. They have evolved to not have a shell and their feet have become wings to give them mobility. The creatures are generally slow moving, but when hunting they are capable of sudden bursts of speed using a special muscle just for this moment of "blood lust."
If you look closely you will see what appear to be horns protruding from their heads. Quite a juxtaposition to their otherwise angelic appearance. These are their sensory organs just like the slugs and snails we know on land. They grow no larger than about two inches long. The sea angels that live in colder waters, such as beneath polar ice, tend to be larger than those in the tropics. They will sometimes gather into large congregations with up to 300 of them per cubic meter.
So now do you believe in angels?
