It depends on which fiction you are taking information from Silver Bloods in the Blue Bloods Series. They are called Sanguines in the Therian Mythos. They are called Crusnik in Trinity Blood. In Vampire: The Masquerade there is a trait called Methuselah’s Thirst that means a vampire has progressed to such an age that human and animal blood no longer satisfies and they must consume the vitae of other vampires.

i read and watched the anime trinity blood and they mentioned crusniks so i became enterested in them and i looked them up. aperntly when a human becomes a vampire and they age they become stronger they can summon a demon after killing the demon they drink the blood of the demon and eat the demon mixing the vampires demonic blood with the demons demonic blood turning them into crusniks .. which feed on humans vampires and demons and are much stronger then any of the 3
