Tiburonia is a genus of jellyfish in the family Ulmaridae. It was erected in 2003, following the discovery of its only species yet identified, Tiburonia granrojo. It was discovered by a crew from MBARI led by George Matsumoto.[2] Its genus name is Tiburonia because the ROV the crew were using was called Tiburon, meaning "shark" in Spanish. Its species name was originally to be called "Big Ugly", but Kirsten Matsumoto raised objections to this name, and renamed it granrojo, meaning "big red" in Spanish.
Tiburonia granrojo is one of the largest sea jellies and unusual in a number of ways. They live at ocean depths of 600 to 1,500 metres (2,000 to 4,900 ft) and have been found across the Pacific Ocean in the Gulf of California, Monterey Bay, Hawaii and Japan. They can grow up to 76 centimetres (30 in) in diameter,[1] according to the California Academy of Sciences, and have thick fleshy oral arms in place of the long tentacles found in most jellies. The entire jellyfish is deep red in color.[3]
To date, only 23 members of the species have been found and only one—a small specimen under 15 centimetres (6 in)—has been retrieved for further study. Several high resolution videos of granrojo have been taken by remote controlled submarines. The discovery was announced by Dr. Matsumoto and colleagues in Marine Biology in 2003.[1]
