Bioluminescent jellyfish

These images from recent deep sea exploration show how weird and wild it is under the sea.

Some of the pictures taken by remote cameras of never-before-seen areas, especially off the eastern Pacific, show what looks like an imaginary world. There’s a delicate jellyfish, an eel with a strange head and a purple disco ball-like critter. And just in time for Halloween, there’s a rare purple vampire squid, nicknamed for its red eyes and deep color. The images are being shown as part of the National Ocean Exploration Forum, October 2016, in New York.

“We’re continually surprised by the variety of life that we find and what we’re seeing,” said Nicole Raineault, science operations director at the Ocean Exploration Trust. “It just underscores what little we know about the ocean and how much more there is to discover out there.”

Vampire squid

A vampire squid (Vampyroteuthis infernalis), a deep-sea cephalopod, is seen during an overnight dive in the Gulf of Mexico, June 27, 2014. Its name comes from its deep color and red eyes, not because it feeds on blood.

Dives in the expedition ranged from 250 to 6,000 meters (820 feet to 3.7 miles) deep.

Hermit crabs usually use a snail or other shell as protection.

Crab and purple orb

A crab, bottom, stands near an unidentified purple orb during a deep sea expedition around the Channel Islands off the coast of California, July 2016. After sampling, it began to unfold to reveal two distinct lobes; researchers thing it may be a pleurobranch sea slug, a close relation to the nudibranch, but currently, none of the known species of California deep-sea pleurobranchs are purple.
