Granrojo or big red, Tiburonia granrojo, is a recently discovered jellyfish of the family Ulmaridae, the only member of its genus yet identified. It is one of the largest sea jellies and unusual in a number of ways.They grow to between 60 and 90 cm (2 to 3 feet) in diameter and have thick fleshy oral 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 15 cm) has been retrieved for further study.
