Jiu-jitsu differs from other martial arts in that ranks are awarded purely by time served -- once achieving the black belt, a practitioner will receive degrees (signified by stripes) on his belt.
The color of the belt will change once a black belt receives seventh degree, at which point they become a red and black belt master (also known as a "coral" belt). Eighth degree is a red and white belt.
The list of those promoted is as follows:
7th degree red and black belt
Jose Henrique Teixeira
8th degree red and white belt
Romero 'Jacare' Cavalcanti
It takes 31 years upon receiving the black belt to achieve seventh degree and 38 years to reach eighth degree.
