List of Red Dwarf concepts

The science fiction series, Red Dwarf, starts some time in the future, but after an accident the protagonist is trapped in stasis for 3 million years. As with many science fiction series, the programme has a few concepts specific to its own fictional universe.

Although there are no sentient alien lifeforms in the Red Dwarf universe, there are a few life forms (all ultimately of terrestrial origin) unique to the programme.

Felis sapiens are a sentient, humanoid species which evolved over 3 million years from a single pregnant domestic cat named Frankenstein, whom Dave Lister bought on shore leave on a colony on Titan. One cat, simply known as "The Cat", is a regular character in the show. Described by Cmdr. Binks of the Enlightenment as "bred from the domestic house cat and about half as smart".

GELF is an acronym for Genetically Engineered Life Form. There are many different GELFs in the show, the first shown was a polymorph in the episode of the same name, but others have become tribal and can act as traders throughout the universe.

The Despair Squid was a creature introduced in Back to Reality. The crew were investigating a crashed ship on an ocean moon, when they realised that there was little or no sealife in the ocean and that every creature in the ship had committed suicide. The squid had evolved a defense mechanism which would cause predators to have a hallucination, group or otherwise, which create sufficient despair, up to the point that the victim would suicide. In Back to Earth, a female squid is seen to cause a further hallucination, though this time one of elation rather than despair.
