An unusual jellyfish was discovered in the Mariana Trench. Scientists have discovered an unusual species of jellyfish that looks like an alien from another planet. The body of the jellyfish with long tentacles glows with red and yellow light. The jellyfish was discovered during the 2016 Deepwater Exploration of the Marianas expedition in the deepest place in the world's oceans - the Mariana Trench. The Mariana Trench, whose depth is 10,994 meters, is a little-studied place due to the complexity of its exploration. Scientists captured a jellyfish on video at a depth of approximately 3,700 meters. It belongs to the genus of jellyfish. Crossota, and it has two sets of tentacles. In the video, the jellyfish's tentacles are extended while the body remains motionless. This behavior suggests that it hunts its prey by luring it into an ambush. The jellyfish was discovered in a mysterious and little-known area of the Mariana Trench called the "underwater peak of Enigma."
