These aliens appear similar to humans, the only differences being two prehensile probosci and a somewhat enlarged nose. People of their species are rare, but they have an impressive lifespan that can last for over a millennium. They tend to behave like vampires. The proboscises lie coiled and hidden in pockets within the cheeks and can be extended to drain a victim's 'luck' or 'soup' by piercing the brain through the nose. The Anzati are capable of mild telepathic control to render their victims paralyzed, and are assassins of legendary skill. The Jedi hunting mercenary Aurra Sing was trained by these assassins, as was the Jedi Master Tholme. Their planet of origin has never been verified, as all sent to investigate the planet suspected to be Anzat are never seen again. Two more famous Anzati were Dannik Jerriko, an assassin of great renown who hunted Han Solo, as written in "Tales From Mos Eisley Cantina. " (Dannik Jerriko appears in person and actually demonstrates killing someone in Galaxy of Fear: Ghost of the Jedi) and the dark Jedi Nikkos Tyris.
The Echani had similar anatomy to that of humans , but were physically distinct due to their light skin, white hair and silver eyes.  They exhibited among themselves a remarkable similarity to each other in their body type and facial features, with close family members such as siblings often appearing indistinguishable to an outside observer.  The Thyrsian subspecies of the Echani, in contrast, shared few of these traits, possessing dark hair and skin, rather than the white hair and silver eyes the Echani became known for.
