The E/V Nautilus team, currently exploring the Galapagos hydrothermal vents, has enocuntered some truly stunning creatures.

The E/V Nautilus expedition crew is currently visiting the Galapagos Rift region and studying the biological diversity of the undersea part of the area. A recently uploaded video shows the team exploring the Galapagos hydrothermal vents and encountering some truly incredible creatures that call the place home.
Among the species spotted during the expedition was the Flamboyant Squid Worm, which was only recently discovered in 2007.
No sunlight reaches the hydrothermal vents and the energy comes from chemicals in the earth's crust, providing sustenance for organisms deep in the ocean.
