Ferengi

The Ferengi are an extremely capatalistic race from the planet Ferenginar.

A Ferengi's entire existance revolves around the aquisition of profit, even above family and friends, according to their sacred Rules of Aquisition.

The current Grand Nagus of the Ferengi Alliance is Rom, who recently avoided an attempt by former liquidator for the Ferengi Commerce Authority, and current Congressman, Brunt, to have him removed from office. (DS9 novel Worlds of Deep Space Nine volume three: "Ferenginar: Satisfaction is Not Guaranteed")

Rom recently appointed his brother, Quark, to the position of Ferengi ambassador to the world of Bajor. (DS9 novel: Unity)

Physiology
The most obvious Ferengi physical trait is the large ear lobes (larger and more pronounced on males than females). This gives the Ferengi keen hearing. The lower ear lobes are also erogenous zones for the Ferengi.

One aspect of Ferengi biology is a specialist type of cells known as pyrocytes. These can provoke a deadly allergic reaction in other species if exposed to them. (TNG episode: The Price)

Another aspect is the Ferengis' four-lobed brains, making them resistant to telepathic or empathic "reading" by species with such powers, like the Betazoids. (TNG episode: ???)

Medical Conditions

 * Dorek Syndrome

Culture & Society
All Ferengi believe in the Great Material Continuum, a spiritual belief that guides them when they accumulate wealth. Only those that follow the Rules of Acquisition are said to travel the 'river' that is the Great Material Continuum.

Those that profit in life and accumulate well are said to be allowed a place in the Divine Treasury. However, those that fail to do so are said to suffer within the Vault of Eternal Destitution as punishment for not following the profit driven ways of the Ferengi.

(DS9 episode: Treachery, Faith, and the Great River, The Dogs of War)

A unique specialist aspect of their language is similar to Human morse code known as B'Zal. This is a pattern of lights in the darkness designed to reveal codes that only another user can identify. (TNG episode: Bloodlines)
