Glaucus Atlanticus. Looks like an alien, but it's real. And seriously poisonous!

This gorgeous little see creature is the Blue Sea Slug Glaucus Atlanticus.

Although this looks like something right off the set of Prometheus, it is actually only a centimetre or two long.

It feeds off the Portugese Man o'War. And here's the punchline - it stores the poison from the Man o'War and can use it itself! More powerful and deadly than its prey...

So what's with this guy handling them then??
