Gorgeous, Weird Jellyfish Found 12,000 feet Below the Surface Near Mariana Trench
The jellyfish in question was filmed earlier this week near the Mariana Trench during a submersible dive to explore an area called the Enigma Seamount. The jellyfish was spotted at a depth of over 12,139 feet. The NOAA researchers identified it as a kind of jellyfish called a hydromedusa, a part of the genus Crossota. Watch a video of it floating around.
“The sepiolid is relatively short-lived, just 3-10 months from egg to its semelparous death. Eggs are 2.0 mm in diameter and laid on the undersides of coral ledges in shallow water. Paralarvae grow very fast; Hanlon et al. (1997) found E. scolopes to breed and lay eggs in the laboratory just 2 months after hatching from the egg. Juveniles are frequently found with adults in shallow water. Adults are sometimes trawled offshore in mid-water in depths to 138 fathoms.” x
This amazing photograph shows a diver in the gap between two tectonic plates. Scuba diver Alex Mustar dived 80 feet into the crevice between North America and Eurasia. The area is near Iceland and it’s full of faults, volcanoes and hot springs caused by the plates gradually separating at a rate of about 1 inch a year.
