'''Granrojo''' or '''Big Red''' (''Tiburonia granrojo'') is the name of a recently discovered form of [[jellyfish]] that is one of largest sea jellies and is unusual among sea jellies in a number of ways. Granrojo live at ocean depths of between 2,000 and 4,800 feet and have been found across the [[Pacific Ocean]] in the [[Sea of Cortez]], [[Monterey Bay]], [[Hawaii]] and [[Japan]]. They grow to between 60-90cm (2-3 feet) in diameter and have tick fleshy arms in place of the long tentacles found in most jellies. They are the only member of a new genus of [[Ulmaridae]] called ''[[Tiburonia]]''.

Granrojo or big red, Tiburonia granrojo, is a recently discovered jellyfish of the family Ulmaridae, the only member of its genus. It is one of largest sea jellies and unusual in a number of ways. Granrojo live at ocean depths of between 2,000 and 4,800 feet and have been found across the Pacific Ocean in the Sea of Cortez, Monterey Bay, Hawaii and Japan. They grow to between 60 and 90 cm (2 to 3 feet) in diameter and have thick fleshy arms in place of the long tentacles found in most jellies.

To date, only 23 members of the species have been found and only one, a small specimen (under 6 inches) has been retrieved for further study. Several high resolution videos of granrojo have been taken by remote controlled submarines. Its discovery was announced by George Matsumoto in Marine Biology in 2003.
