Tiburonia is a genus of jellyfish in the family Ulmaridae. It was only recently discovered in 2003 by a crew from MBARI led by George Matsumoto. The specific species of jellyfish was supposed to be called “Big Ugly”, but there were objections so instead they called it “Big Red.”
They have most frequently been found at the ocean depths of 600 to 1,500 metres. These jellyfish have been found across the entire Pacific Ocean in the Gulf of California, Monterey Bay, Hawaii, and Japan.
These jellyfish are able to grow up to 76 centimetres (30 inches) in diameter. As of right now, there have only been 23 members of the species discovered. This jellyfish will use four to seven of its “fleshy feeding arms” to capture its prey. Just to confirm, T. Granrojo is not a new species or genus, but instead it was just so different from other jellies it was assigned to a new subfamily.
