Leviathan (Farscape)

The Leviathans are a semi sapient race of biomechanical spaceships from the Farscape universe.

Biology
Although being a race of spacefaring vessels, they apparently have different genders and posses the ability to reproduce using some kind of womb complex inside the Leviathan. They are also a symbiont species with the Pilot species.

Leviathans live for several hundred years, the presence of a pilot's affect on their lifespan is unclear.

Culture
Despite being only semi-sapient they appear to have a cultural and traditional burial ground (although the location of which is a secret) where all Leviathans go to die.

History
Being a symbiont species, they have a long history with the Pilots going back possibly to their very creation.

The Leviathans were built by a race called the Builders.

Procreation and Sub Species
Only one instance of Leviathan reproduction is known, this being Moya's son Talyn, although he was not a true Leviathan as he was a Sebacean attempt to make a weaponized hybrid and as such could possibly be classed as a sub species.

Although Talyn never reached maturity as he sacrificed himself to save the crew of his mother, it is thought he would have grown even larger and being a warship even more powerful than normal Leviathans. Also unlike all other Leviathans he had the ability to manipulate his pilot to a degree another adaptation he possessed was the ability to join with multiple hosts and species including; Sebacean and Scarran.

Another aspect of his physiology was that as he grew, so did his weapons.

Faster than light
All Leviathans appear to have the ability to "jump" from one point in space to another, potentially many light years.This is called a Star Burst, this ability seems to be much faster than other modes used by other people's such as the Scarran empire and the PeaceKeeper Corps who appear to be easily out run by the Leviathan Moya whenever she Star Bursts.
