Researchers say the creature say it "does not resemble anything seen before" after filming it at 7,000 metres below sea-level.
A bizarre jellyfish-like creature has been discovered at the bottom of the Indian Ocean in what is believed to be its first ever sighting.
The unnamed creature was captured on camera at the murky depths of the Java Trench, some 7,000 metres below sea level.
Footage shows the deep-sea alien slowly floating across the ocean floor while emitting a haunting blue glow.
The leader of the expedition, Victor Vescovo, said the jellyfish “does not resemble anything seen before”.
