Check Out an Up-Close Video of a Marine Organism Made Up of Other Marine Organisms

Fun fact: the ocean is home to creatures called siphonophores—an order of Hydrozoa that aren’t actually individual organisms but colonies of sea creatures that work together to act as one and generally resemble jellyfish. The Portuguese man o’ war is actually a siphonophore, and this amazing video of another species comes from Nautilus Live, an expedition run by the person who found the Titanic, Dr. Robert Ballard.

For more amazing sea life, you can watch live video of the ocean’s floor from the expedition on the Nautilus Live website. (The ship is currently docked as of this writing.)
