Hutt (Star Wars) - Physiology

Physiology

Adult Hutts are shaped rather like extremely large shell-less gastropods or slugs (up to one thousand kilograms) with stubby arms, no rear limbs and numerous redundant internal organs. Locomotion is through a series of rippling contractions akin to a slug's locomotion. In the novelization of Return of the Jedi, it is mentioned that Hutts are born bipedal, but their legs grow together over time due to lack of movement. Hutts are long-lived, with a lifespan of up to a thousand years, reproducing asexually and nursing their young in pouches not unlike marsupials. An infant Hutt, known as a Huttlet, is the size of an orange when born, and lives in the parent's pouch for five decades before becoming "fully developed." Adolescents become adults when they reach the age of 130 years. Though traditionally referred to as males, all members of the species are hermaphroditic; personality type and gender roles are assumed voluntarily, or upon a viewer's deduction. Upon becoming pregnant, Hutts are referred to as female, although some Hutts do not accept this and choose to retain their masculine persona, whereas others alternate between male and female character.

Hutt skin is extremely thick, and when combined with their redundant organs and tough flesh, can result in Hutts being able to survive direct blaster fire hits. Hutts are also inedible by most life forms, including Sarlacci, resistant to the Force due to their unique thought patterns, and are able to see the ultraviolet and infrared portions of the electromagnetic spectrum.
